What is Data Interpretation and Logical Reasoning (DILR) in the CAT 2023 exam?

The Data Interpretation and Logical Reasoning sections are among the most crucial in any management entrance exam. You can find them in exams such as CAT,  XAT, IIFT,  SNAP, NMAT, CMAT, and MAT. In some exams, the DILR section is common but in others, they can be treated as separate sections.

DI is the most calculation-intensive section. It has a plethora of charts and tables from which you must extract and interpret information.Logical Reasoning is all based on how one can approach problems with an analytical mindset, and crack and decode the logic behind the question given. It only comes with practice.Basic knowledge of bar charts, line charts, histograms, pie charts, percentages and ratios are required to understand the pattern of questions and answer with precision and accuracy. The candidates must be strong with their fundamentals of mathematics and basic problem solving with numbers to ace this section. This section is to be given as much importance as any other section in any management exam for any B-School around the country, as it is a scoring section if the fundamentals are clear and the candidates have enough practice and exposure towards solving different types of problems, from online mock tests, free test series and books recommended by MBA Rendezvous.

You need to understand the fundamentals of DI & LR hence, MBA Rendezvous has provided you with the following questions with solutions.

Let Us Take You Through Some Important CAT DI & LR Questions.

Is DILR (Data Interpretation and Logical Reasoning) tough in the CAT exam?

Yes. Data Interpretation and Logical Reasoning (DILR) in CAT is tough. The most complex part of the DILR section is the Analytical Puzzles, which are wholly unpredictable and thus tricky to resolve.The candidates must be strong with their analytical thinking and must be able to easily identify the problem statement once presented to them. Students must keep practising a variety of puzzles before entering the actual exam, as this will give them more confidence and exposure. Many puzzles are available online and are also provided by MBA Rendezvous for students to practise, better their skills and understand their weak points. Gradually, the DILR section will start seemingly familiar and students will be able to easily crack the logic to the questions habitually.

Students can also attempt some sectional tests specifically for DILR if they find themselves to be weak in that particular area as compared to the other 2 sections in CAT exams or any other B-school exams. There are topic wise tests also that focus on strengthening candidates’ understanding of how to approach a problem when given, and how the pattern of questions seems on the actual day of the exam.

1.          To get one kg. of Protein we need to spend

             Rs. (40x100)/50 = Rs.80 in case of Soya Products,

             Rs.(60x100)/40 = Rs.150 in case of Red Meat,

             Rs.(35x100)/25 = Rs.140 in case of Milk Products and

             Rs.(50x100)/25 = Rs.200 in case of Cereals.

Hence, (d)

2.             The cost of one gram of Carbohydrates from Soya products = (40x100)/(25x1000) = Rs.4/25

               The cost of one gram of Carbohydrates from Red Meat = (60x100)/(30x1000) = Rs.2/10

               The cost of one gram of Carbohydrates from Milk Products = (35x100)/(25x1000) = Rs.14/100

               The cost of one gram of Carbohydrates from Cereals = (50x100)/(45x1000) = Rs. 1/9

Hence the desired ratio =

3. Cost of Protein per kg. from Soya Products in 2004-2005

= (50x100)/50 = Rs.100

Cost of Protein per kg. from Red Meat in 2004 – 2005

=(55x100)/40 = Rs.137.5.

Cost of Protein per kg. from Milk Products in 2004-2005

=(30x100)/25 = Rs. 120.

Cost of Protein per kg. from Cereals in 2004-2005

=(50x100)/25 = Rs.200.

Desired price =(100+137.5+120+200)/4 = Rs.140.

Hence, (c).

27. (a) Total time taken (in hrs.) to produce 5000 units each of E, F, G and H:

For Machine A

= 5000/75 + 5000/150 + 5000/125 + 5000/50

= 5000(1/75 + 1/150 + 1/125 + 1/50)

= 200(1/3 + 1/6 + 1/5 + 1/2) = 240

For Machine B :

= 5000(1/125 + 1/75 + 1/100 + 1/100)

= 200(1/5 + 1/3 + 1/4 + 1/4) = 206.67

For Machine c :

= 5000(1/100 + 1/125 + 1/125 + 1/75)

= 200(1/4 + 1/5 + 1/5 + 1/3) = 196.67(least)

For Machine d :

= 5000(1/125 + 1/75 + 1/75 + 1/125)

= 200(1/5 + 1/3 + 1/3 + 1/5) = 213.33

28. (c) Observation of the table tells us that the answer shouldbe A-F, B-E, C-G, D-H.

29. (b) Let n units of each item be produced by machine A:

Hence, n/75 + n/150 + n/125 + n/50 = 4

=> n(1/75 + 1/150 + 1/125 +1/50) = 4

=> (n/25)(1/3 + 1/6 + 1/5 + 1/2) = 4

=> n = 100/1.2 = 83.33

Let k units of each item be produced by machine B:

Hence, k/125 + k/75 + k/100 + k/100 = 4

=> k(1/125 + 1/75 + 1/100 + 1/100) = 4

=> (k/25)(1/5 + 1/3 + 1/4 + 1/4) = 4

=> k = 100/1.033 = 96.77

At maximum, 4× 96 = 384 units can be produced by machine B.
Hence, 4k = 384
Ratio = 332 : 384 = 83 : 96.

Directions for questions 30 to 32 :

Let us analyse the scores of Match-1 first:

Runs scored by Bimal, Dinu and Elan = 88 + 72 + 60 = 220

Hence, runs scored by Arpit and Chatur = 270 – 220 = 50

Also 10% of 270 = 27

So, both Arpit and Chatur can score a maximum of 27 runs but the sum of their scores should be 50.

Arpit’s score’s range in Match-1 is 23–27 and subsequently Chatur’s score’s range in Match-1 is 27–23.

Similarly Chatur and Dinu scored 30 runs each in Match-2.

In Match-3 even though 10% of 240 = 24, as Dinu scored 20 runs, both Arpit and Bimal can score a maximum of 19 runs, but the sum of their scores should be 32.

In Match-4, Chatur and Elan combined scored 200 – 53 – 52 – 56 = 39 runs. As 10% of 200 = 20, one of Chatur or Elan scores 20 runs and the other scores 19 runs.

The table can be re-written as :

  Match-1 Match-2 Match-3 Match-4
Runs scored by player Arpit 27–23 100  19–13 53
Bimal 88  65 13–19 52
Chatur 23–27 30 110 19–20
Dinu 72 75 20 56
Elan 60  30 78 20–19
Total 270 300 240 200

 

30. (a) Maximum possible runs scored by Arpit in Match-1 = 27

Maximum possible runs scored by Arpit in Match-3 = 19

Maximum possible percentage contribution:

(27+100+19+53)/(270+300+240+200)x100% = 199/1010x100%
= 19.7%

31. (b) Maximum possible total runs scored by Chatur in the four matches = 27 + 30 + 110 + 20 = 187.

In such a case minimum possible total runs scored by Arpit in the four matches = 23 + 100 + 13 + 53 = 189.

Difference = 189 – 187 = 2 (minimum possible) Subsequently total runs scored by Bimal in the four matches = 88 + 65 + 19 + 52 = 224.

Also, total runs scored by Elan in the four matches = 60 + 30 + 78 + 19 = 187

Absolute difference = 224 – 187 = 37

32. (c) Individual ranges for total score:

Arpit-> 189-199

Bimal-> 218-224

Chatur-> 182-187

Dinu-> 223

Elan-> 187-188

Least total will be of Chatur (Rank 5)

2nd least will be Elan (Rank 4)

Rank 3 must be of Arpit.

It is not possible to determine the exact ranks of Bimal and Dinu.

33. a

34. (c) Total sales in South Asia = 9000 units

Total sales in West Africa = 4500 units

Total sales in East Europe = 1500 units

Hence, the required ratio is 6 : 3 : 1.

35. (c) Statement I :

Total sales of Laptops in South America will be the sum of sales of HP, Compaq, IBM and Sony which is equal to 3000 units. So statement I is correct.

Statement II :

Sales of IBM in East Africa = 517 units

Sales of HP in West Africa = 180 units

Thus it is not 25% more. So statement II is incorrect.

Statement III :

Sales of Compaq in North America = 540 units

Sales of Compaq in South America = 1260 units

Ratio = 3 : 7. So statement III is correct

Directions for questions 36 to 38 : We can make the following figure based on the information given in the question.

Mock Questions on Data Interpretation and Logical Reasoning

GAR –  Good Academic Record
ECA –  Extra Curricular Activities

36. (d) From the figure it can be inferred that the answer must be ‘20 – x’. As we don’t know the exact value of x the answer cannot be determined.

37. (c) must be the maximum possible value of ‘y’. As the number of students who have ECA and who have also written BAT but have no Work Experience is ‘14 – y’, we can say that the maximum possible value of ‘y’ must be 14.

38. (b) Answer = 21 (No Work Experience) + 14 (Work Experience) = 35

Directions for questions 39 to 41 : Total marks obtained by S1, S2, S3, S4 and S5 are 148, 125,121, 144 and 127 respectively. As Anup obtained 50 marks in Chemistry, he can be disguised either as S1 or S2.

Rohan can either be disguised as S1 or S2 and accordingly Himanshu must be disguised as either S4 or S3.

Based on the given data, we arrive at the following cases

  Case I Case II Case III Case IV
S1 Anup Anup Rohan Rohan 
S2 Rohan Rohan Anup Anup 
S3 Himanshu Himanshu  Vishal Sudip
S4 Vishal Sudip Himanshu Himanshu
S5 Sudip Vishal Sudip Vishal

39. (d) It is clear from the above table that one of Himanshu,Vishal or Sudip is disguised as S3.

40. (d) Let us consider all the options one by one.

(i) If statement I is true then Sudip must be disguised as S5 and his total score in all three subjects must be 127.

Subsequently from Case I and Case III, Himanshu can be disguised as either S3 or S4. Hence, Himanshu’s total score will be either 121 or 144. Therefore we cannot say that statement II is definitely true.

(ii) If statement II is true then Himanshu, as his score cannot be the lowest, must be disguised as S4. Now, Sudip must be disguised as either S3 or S5. Hence, Sudip’s score in chemistry is either 43 or 36. Therefore we cannot say that statement I is definitely true.

(iii) If statement I is false then Sudip must be disguised as either S3 or S4. Now, if Sudip has been disguised as S3 then Himanshu must be S4 (Case IV) and his total score (144) will be more than that of Sudip (121). But if  Sudip has been disguised as S4 then Himanshu must be S3 (Case II) and his total score (121) will be less than that of Sudip (144). Therefore we cannot say that statement II is definitely false.

41. (a) Himanshu obtained the highest marks in Mathematics. If we assume this to be true, then he must be S4. In both Case III and Case IV, Rohan is disguised as S1,who obtained the highest marks (148) in all the threesubjects combined.

Directions for questions 42 to 44 : Statement 1 indicates that Feroz and Himanshu are at seat number 7 and 6 respectively.

Tarun is the only person between Feroz and Shivku while Aashu is opposite Tarun (Statement 3). Hence, Aashu, Tarun and Shivku must be at seat number 5, 8 and 9 respectively.From Statement 2 we get the following figures that depict the possible seating arrangements for the 12 people:

Mock Questions on Data Interpretation and Logical Reasoning

42. (d)  If Shivku is not sitting opposite Vijay then either Vijay (from figure 1) or Jatin (from figure 2) is sitting next to Manoj.

43. (d) If Manoj is not sitting next to Vijay then there are six possible arrangements (2 from figure 1 and 4 from figure 2)

44. (a) Manoj, Feroz and Himanshu occupy three of the four corner seats and it is known that Feroz is sitting opposite Himanshu. Hence, Sajid can only sit opposite Manoj. This can also be seen from figure 1

Directions for questions 45 to 46 :

45. If the mystery novel is written by Ovattio then the arrangement looks like :

Genre    Mystery  Horror  Comedy  Thriller 
Publisher Rajveer/ Sarka Quattchori Purshottam  Sarkar/ Rajveer
Author  Ovattio  Lalu/Monu Monu/Lalu Nonu

46. The author of the mystery novel can be Lalu or Monu or Ovattio.If the author is either Lalu or Monu then the publisher can be Purshottam only. If the author is Ovattio then the publisher can be either Rajveer or Sarkar

47. (c) In terms of increasing number of candies received, the possible sequence can be:

either   Mohan < Ram < Raja < Roy or Mohan < Ram < Roy < Raja

The above order clearly shows that Ram receives at least 2 candies. Possible sets for candies received by Ram and Roy will be (2, 6) and (3, 7).

Note: The case (4, 8) etc. are not possible as then the other two values will become less than 4 each. Subsequently only possible sets for overall distribution are:

  Raja Ram Mohan Roy 
Number of candies Case 1 7 2 1 6
Case 2 5 3 1 7
Case 3 4 3 2 7

Thus, Raja can have 7 or 5 or 4 candies.

∴ Maximum possible difference = 7 - 4 = 3

48. (d) According to Statement 1, B can only live on the 2nd or the 3rd floor (Statement 4 says that B does not live on 1st floor).But if B lives on the 2nd floor and hence A on the 7th, is not possible to fit in the floors for D, F, H, C and E (see Statements 2 and 3). Hence B and A must live on 3rd and 8th floor respectively. H, C and E live on 3 adjacent floors, so they must live on floors between B and A.Subsequently as D and F are also on adjacent floors, they must live on 1st and 2nd floor (not necessarily in that order). Some of the possible distributions are:

Floor  1 2 3 4 5 6 7 8
Person  D F B G E H C A
D F B C H E G A
F D B E H C G A
F D B G C H E A

It can be seen that D will live on either the 1st or the 2nd floor. Also, C’s floor would be one of 4th, 5th, 6th  or 7th.

So the possible values of N: 6, 5, 4, 3, 2

Total possible values of N = 5

49. (d) If Statement III made by Billu and Chiklu are not true then in that case both Amar and Billu will be having the blue ball which is not possible. Hence, Amar ’s third Statement is definitely not true.

If we assume that Billu’s 3rd Statement is also not true (and hence Chiklu ’s is true), the arrangement will be:

Amar Billu Chiklu 
green, blue red, yellow pink, black

If we assume that Chiklu's 3rd Statement is not true (and hence Billu's is true), the arrangement will be:

Amar Billu Chiklu 
green, yellow red, blue pink, black

Hence, it cannot be determined

50. Let us assume that the accident happens at point A. Hence PA and AQ would be the distances covered by the train from P to A and A to Q respectively.

Mock Questions on Data Interpretation and Logical Reasoning

Let the speed (in km/min) before and after the accident be ‘v’ and ‘u’.

Total time taken by the train had the accident not taken

place = PQ/V=(PA+AQ)/V

Total time taken by the train due to accident

= PA/V+AQ/U = PQ/V+16 = PA/V+AQ/V+16

Hence, AQ (1/u-1/v) = 16

From Statement A:

In this case let us assume that the accident happens at point B. Following a similar method as mentioned above we get:

BQ(1/U-1/V) = 21

Or (AQ+10)(1/U-1/V) = 21

From (i) and (ii):

AQ = 32 km and hence, PQ = 30 + 32 = 62 km

From Statement B:

In this case let us assume that the accident happens at point C. Following a similar method as mentioned above we get:

CQ(1/U-1/V)=20(1/U-1/V) =12

From (i) and (iii) :

AQ = 80/3 km and hence, PQ = 30 + 80/3 = 170/3 km.

So the question can be answered by using either of the statements alone.

51. (c)  To find Mohan’s age on 31st December, 2000 we need to find his year of birth.

From Statement A:

There are multiple possibilities for the year of birth of Mohan - 1953, 1959, 1971 etc. Hence, Statement I alone is insufficient to answer.

From Statement B:

There are multiple possibilities for the year of birth of Mohan’s son - 1953, 1971, 1997 etc.Hence, Statement II alone is insufficient to answer.

Combining Statement A and Statement B:

Possible years of birth for Mohan and his son are ‘1959 and 1983’ or‘1973 and 1997’. It is still not possible to get a unique solution.Hence the question cannot be answered even by using both the statements together.

Directions for questions 52 to 56 :  As Subbu performed alone in the first slot on the second day, the bands could not have performed more than 5 times.  So the number of performances given by the bands was either 4 or 5. If the number of performances given by the bands was 4, then each of the four artists would have given one performance. However, in that case the sum of the number of performances given by Mitti, Kehsanloy and Kumar  respectively would be 3 (a prime number), which is not possible. So the number of performances given by the bands as well as by the artists must be 5. The number of performances given by Delhi Sea and Mitti must be the same and it should be 1 each only. The number of performances given by GTH was 3. Either Kehsanloy or Kumar gave 2 performances and the rest 3 artists gave 1 performance each.

As the last performance of Shankar was held before the first performance of GTH, Delhi Sea and Mitti must have performed successively in the first two slots on the first day. Shankar must have performed in either the first slot or the second slot on the first day.

The conclusions made thus far can be tabulated as given below.

Slot Slot-1 Slot-2 Slot-3
Day
Day-1 - - -
Delhi Sea Mitti GTH
Day- 2 Subbu - -
NA GTH GTH

52. (c) The given information can be tabulated as:

Slot Slot-1 Slot-2 Slot-3
Day
Day-1 Shankar NA Kehsanloy
Delhi Sea Mitti GTH
Day- 2 Subbu Kumar Kehsanloy
NA GTH GTH 

53. (b) Kumar must definitely have performed with GTH as GTH performed in both the second and the third slot on the second day.

54. (d) All the given statements could be true.

55. From Statement A:

As the sum of the number of parking slots in Mohit’s house and Pranab’s house is an even number, the number of parking slots in each of Pavan, Pranab and Mohit’s house is one and the number of parking slots in Santosh’s house is two. Also, Santosh must be staying in the second largest house. Hence, this statement alone can answer the question.

From Statement B:

The houses of Pavan, Pranab, Mohit and Santosh have three, three, five and two parking slots  respectively. It is also known that the largest house cannot have five parking slots. But we cannot deduce anything about
the second largest house. Hence, this statement alone cannot answer the question.

56. It can be concluded that nobody except Bhanu and Deepak likes Dancing as the number of children who like Dancing cannot be more than two. Also, Deepak doesn’t like Rowing and Running, both of which are
liked by Aman. SInce Deepak likes Sketching, it is not liked by both Aman and Bhanu. So Chaman and Elhan like Sketching. The conclusions made thus far can be tabulated as shown below.

  Rowing Singing Dancing Sketching Running
Aman Yes   No No Yes
Bhanu     Yes No  
Chaman     No Yes  
Deepak No   Yes Yes No
 Elhan     No Yes  

The two children who like exactly the same set of activities must be Chaman and Elhan (this can be seen from the table). Since at least three children like Running, Chaman and Elhan must be two of them. It cannot be determined whether Bhanu likes Running or not.

Directions for questions 57 to 62 : Let N(1) = N(6) = a, N(2) = N(5) = b, N(3) = c and N(4) = d. Here a, b and c are distinct (as given). Also, b and d cannot be the same. Hence, 2a + 2b + c + d = 10 (the total number of people).

⇒ 2(a + b) + c + d = 10

The least possible value of ‘a + b’ is 3 and it is evident from the above equation that none among a, b, c and d can be greater than or equal to 4. The only possible integer solution to the above equation is when a, b, c and d are equal 1, 2, 3 and 1 respectively.

The following table can thus be concluded:

  Number of occupants  Name of the occupants 
Floor 6 1 ?
Floor 5 2 ?
Floor 4 1 ?
Floor 3 3 ?
Floor 2 2 ?
Floor 1 1 ?

From statement (ii) and the above table it is evident that Chuck’s floor number is greater than 3 and hence from statement (i) and the above table it can be concluded that Chuck and Berry
live on floor 5. Subsequently, Kirk and David live on floor 4 and floor 3 respectively. Clapton, Jimmy and Hammett must occupy floor 1 and floor 2 (in no particular order), as they live below
David. From statement (iii) it can be concluded that Gilmour and Page live on floor 3 with David. Finally, it can be concluded from statement (iv) that Jimmy and Eric live on floor 1 and floor
6 respectively. The table can be completed as given below.

  Number of occupants  Name of the occupants 
Floor 6 1 Eric
Floor 5 2  Chuck, Berry
Floor 4 1 Kirk
Floor 3 3 David, Gilmour, Page
Floor 2 2 Clapton, Hammett
Floor 1 1 Jimmy

57. (b) Difference = 3 – 2 = 1

58. (a) Eric lives on floor 6

59. (c) Jimmy lives alone on floor 1. The rest 9 people live on floors higher than his.

60.(c)  he sequence should start with sentence C as it introduces a topic– the repercussions of the art-market boom. C is followed by E (as there is a reference in the plural ) and both sentences are linked with the reference to museums. E also is an elaboration of the point being made in sentence C. D and A are clearly linked through the reference to the annual booklet. B comes in as the ending sentence as it mentions the consequence of the weakening in the buying power of museums. The correct sequence is CEDAB, option (c).

61.  From (iii), as Shama and Hema are in the same car, Radha must be in a different car. From (v), either Divya or Charu must be in the same car as Radha and the other must be in the same car as Kiran. As Vicky cannot be in the same car as Hema, Kiran or Charu, he must be in the same car as Radha and Divya. From (i), Hari and Naresh are in the same car with Shama and Hema. Further analysis leads to the following table:

Case I 
Car I: 
Radha-Pankaj
Divya-Vicky
Car II:
Shama-Hari
Hema-Naresh
Car III:

Mock Questions on Data Interpretation and Logical Reasoning

Directions for questions 63 to 64 : Let the total money spent in 2006 be x and the money spent in 2007 be y.

64. (d)   For India:  12% of x = 15% of y ⇒4x = 5y

For China in 2006, 16% of x = 16%× 5y/4 = 20% of y

Let the percentage of money spent in China in the year 2007 be p.

p% of y = 25% of 20% of y⇒p = 5

65. (a) The percentage of money spent in Britain, America and Africa together in 2006 = 60%

The percentage of money spent in Britain, America and Africa together in 2007 = 70%

60% of x – 70% of y = 32

60% of –5y/4- 70% of  y = 32

5% of y = 32

y = 640 dollars

The percentage of money spent in Australia in the year 2007 = 100% – 90% = 10% of 640 =  64 dollars.

Directions for questions 65 to 67 :

65. (b) The Unhealthiness Index is maximum for the year 2003 and the value is

= 2,00,000x(1.2)(0.85)(1.1)(1.2)/5200=51.8

66. (c) The number of patients in 2008 = The number of patients in 2006 × (0.7)2 which comes out to be 95,596.

The number of hospitals in 2008 will be = 5700× (1.1)2 = 6897

Therefore, Unhealthiness Index 95,596/6897= 13.86

67.(d) As per the given data (using graph information), the number of patients in 2006 = 1,95,093. The number of patients in 2007 will be 1,95,093 × 0.6= 1,17,056. To have an Unhealthiness Index of 15, the number of hospitals

needed will be 1,17,056/15 = 7804. Therefore the percentage increase needed in the number of hospitals will be (7804 – 5700)/5700 ×100= 36.9%

Directions for questions 68 to 69 :

Mock Questions on Data Interpretation and Logical Reasoning

The number of employees who are not chefs = 100 –18x – y

68. (b) 100 – 18x– y = 40

and y = 6⇒18x = 54⇒x = 3

The number of chefs who can’t make Continental= 15 + 15 + 3 = 33

69. (c) 100– 18x– y > 5x⇒23x + y < 100

The maximum possible values of x is 4.

Hence, the maximum possible number of chefs who can make exactly one cuisine = 15× 4 = 60

Directions for questions 70 to 72 : From Statement (i): The person who likes B4  also likes C1.

From Statement (ii): M3 does not like C3. Also, the person who  likes B3  likes his own car.

Using Statement (i) and (i): The 2 possible cases are:

Case I: M2 likes B3 and C2.

Using Statement (i), we can say that M4 does not like B4.Hence M3 likes B4 and C1

    M1 M2 M3  M4
Likes the bike   B3 B4   
Likes the car   C2 C1  

But in this case B3 should be liked by M1, which is not true. So this case is not possible.

Case II: M4 likes B3 and C4.

B4 cannot be liked by M3 and so B4 is liked by M2

 

    M1 M2 M3  M4
Likes the bike B2 B4 B1 B3 
Likes the car C3 C1 C2 C4

So the complete table looks like:

    M1 M2 M3  M4
Likes the bike   B4   B3 
Likes the car   C1 C1 C4

70. (d)

71. (b)

72. (c)

Directions for questions 73 to 74 : A, C, E and F can be arranged amongst themselves in two ways:

Mock Questions on Data Interpretation and Logical Reasoning

73. (c)  Akhil can sit in 4 different positions - 1, 2, 3, 5 (from the left).

74. (c) There are two such cases - 1c and 2a

75. (a)  Irrespective of whether a person is from Jupiter or Earth, he would always say that he is not from Jupiter. Hence, Sharad has spoken the truth about Lallu. But Budha says that Sharad is from Jupiter (and hence a lier). So Budha has definitely lied and Budha himself must be from Jupiter.

76. (a) Let us assume that the number of goals scored by Rooney, Messi and Torres before the World Cup are R, M and T respectively.

∴ R + 7 = T  and T + 8 = 2M
From Statement A:

R + M = 21

By solving the equations we get the values:R = 9, M = 12 and T = 16.

From Statement B:

Absolute difference between goals scored by Rooney and Messi is 3.
∴R– M = 3 or M– R = 3.

So either ‘R = 21, M = 18 and T = 28’ or ‘R = 9, M = 12 and T = 16’.

We do not get a unique set of values.

Hence, the question can be answered by using Statement A alone but not by using Statement B alone

77. (d)  If P is true then S is true. (Given) So if S is false then P must be false.                                                                                         ...(1)

If both R and S are true then T is false. (Given) So if T is true then atleast one of R and S must be false.                                                     ...(2)

Conclusion (2) can be re-written as follows using Conclusion (1):

If T is true then atleast one of R and P must be false.

78. (d)  Both Team 1 and Team 2 have 1 girl and 2 boys each. So among A, C, E, B, D and F there are 2 girls and 4 boys. So the remaining person i.e. G must be a girl. Similarly, from Team 3 and Team 4 we can find out that C must be a girl. Also, A must be a boy as he is there with C in Team 1.

79. (d)  Let us write down all the possible ranks for each of the persons in a tabular form.‘0’  denotes a rank which is not in the top 3.

          A E
Using only basic information 0/1 0/2/3 0/1/3 0/1/2/3 0/1/2/3
Using Statement A 0/1  0/3 0/1/3 2 0/1/3
Using Statement B 0/1 0/2/3 0/1/3 0/1/2/3 2/3
Using Statement A and B together 0/1 0 0/1 2 3

Hence, the exact ranks of A and C cannot be found out even after combining the two statements.

Directions for questions 80 to 81 : 

80. (c) We can say that the total fare of : Delni-Bhokal + Bhokal-Mumtai = Mumtai-Delni + Rs.125.

Hence, the variable fare of: Delni-Bhokal + Bhokal-Mumtai = Mumtai-Delni + Rs.65.

This is possible only if Mumtai-Delni falls in the distance range 1001 – 1800 km (Rs. 340).

One of Delni-Bhokal and Bhokal-Mumtai falls in the range 151 – 500 km (Rs. 155) and the other falls in the range 501 – 1000 km (Rs. 250).

81.(c)  Yatri Kumar must have travelled in a Passenger train. 

First day: Fare in the Sleeper Class for the distance range 1001 – 1800 km = Rs. 160 + Rs. 60 = Rs. 220.

Second day: Fare in the Air Conditioned Class for the distance range ≤150 km = Rs. 120 + Rs. 100 = Rs. 220.

Directions for questions 82  to 84 : 

82. (a) a Absolute percentage change in the total sales of Naruti uzuki Ltd. from pril to July =(5670 - 5250)/5250 x 100 = 8% 

Absolute percentage change in sales of Dwift from April to July 75-69/75 x 100=8%

83. (d) Sales of the other car models of Naruti Kuzuki Ltd. in May 2010 = 549000 – (50 + 72 + 51 + 52)×1000= 324 × 103

Sales of the other car models of Naruti Kuzuki Ltd. in July 2010 = 567000 – (42 + 63 + 33 + 69) × 1000 = 360 × 103

Percentage increase

(360-324)/324x 100 = 11.11%

84. (b) The ratio of the sales of Sezire to the total sales of cars by Naruti Kuzuki Ltd. in:

April = (49X1000)/(5250x100)=7/75

May = (72X1000)/(5290x100)=8/61

June = (72X1000)/(5580x100)=8/62

July = (63X1000)/(5670x100)=1/9

So the ratio is the highest for May. 

Directions for questions 85  to 87 : The table given below can be formed from the data given in the question.

Commodities Maize Rice Sugar Cane Cotton Mustard Seeds
Total production cost (Rs. lakhs) 90 75 105 160 140
Profit per ton (Rs. lakhs) 30 15 20 15 40

 

85.(b) Profit percentage per ton for :

Maize = 30/90x100 = 33.33%

Rice = 15/75x100 = 20%

Sugar Cane = 20/105x100 = 19.05%

Cotton = 15/160x100 = 9.375%

Mustard seeds = 40/140x100 = 28.75%

So the profit percentage per ton is the highest for Maize

86. (c) Two - Sugar Cane and Cotton.

87.(c)  Total quantity of raw material used in production of 1 ton of Cotton

= (27x105)/54 = 50,000 kg

The total area of land required

=10/200x50,000x103

=2500000 m2 = 2.5 km2

Directions for questions 88 to 90 : Let’s first form as many teams as possible out of the six people Alok (A), Bharti (B), Chaman (C), Dinu (D), Ekant (E) and Faisal (F).

Teams with 2 members :

A cannot be in any such team as otherwise at least one of B and C must be selected and then subsequently one of D and E must be selected as well (hence exceeding 2 member size). Possible teams are:
1.  B, D
2.  C, E
3.  D, E
4.  E, F
Teams with 3 members  :

5.  A, C, E
6.  A, B, D
7.  C, E, D
Teams with 4 members :

8.  A, B, D, F
9.  A, C, E, D

Note: No other team size is possible

88. (b) Possible teams without B and F are:
1. C, E
2. D, E
3. A, C, E
4. C, E, D
5. A, C, E, D

We can see that Ekant (E) should definitely be selected.

89. (d) Ekant (E) and Faisal (F) (team number 4) appear together only once and their pair is not selected with any one else out of the remaining 4 people.

90. (d) Team selected must be either A, B, D, F   (team number 8) or A, C, E, D   (team number 9) We can see that Alok (A) and Dinu (D) both are definitely selected in the team

91. (b)

Positions  1 2 3 4 5
Positions1  T R Q P S
Positions2 S P T R Q
Positions3 S R Q P T
Positions4 Q S P T R
Positions5  S R  Q T P

S cannot be at the 1st position as it has been predicted by three persons. Similarly R and Q cannot be at the 2nd and the 3rd positions respectively. So in Prediction 3 the first three positions are definitely incorrect. Now if we assume that exactly two positions are correct in Prediction 3 then P is at the 4th position and T must be at the 5th position. But as a result 4th becomes the only correct position in Prediction 1 which is not possible. Hence all the positions in Prediction 3 must be incorrect. Similarly all the positions in Prediction 1 and Prediction 5 can also be proved incorrect and Prediction 2 and Prediction 4 have exactly two correct positions each. Now it can be answered by observing the options. 

Alternate solution:

The options ‘QPSTR’ and ‘QTPSR’ cannot be correct as in both the cases Prediction 4 would have given the correct positions for three runners which would contradict the information given in the question. Similarly the option ‘QPTRS’ cannot be correct as Prediction 4 would have given the correct position for only one runner. The only option left is ‘QPTSR’ which must be correct.

92. (c) From the first statement: E, G, D < B < F

From the second statement: A, D < C < E

From the third statement: G < F, E

Combining the three statements we get:
 A, D < C < E < B < F

 G < E < B < F

C, G is the only possible pair of twins from the given options 

93. (b) Two men will see three hats of the same colour, and one hat of a different colour. Since they know that there cannot be four hats of the same colour, they can deduce that their hat colour is the same as that of the man with the different coloured hat. So two people will know their hat colour. The other three people will see two black and two white hats and so they won’t be able to know the colour of their own hats.

94. (a) Mock Questions on Data Interpretation and Logical Reasoning

From Statement A:

Mubashir would be at Door 1 and Himanshu at Door 2.

From Statement B:

If one stops after an odd number of tosses he should be at the door which is odd number of steps away from him initially. Hence, Mubashir and Himanshu should be at Door 1 and Door 2 respectively. Hence the question can be answered by either Statement alone

Directions for questions 95 to 96 : From Table-2 the number of Orange trees planted on Day 3 is 7. Therefore, Bobby (B) and Chetan (C) must have planted Orange trees on Day 3. From Table-1 and Table-2, Ashish (A)planted Coconut trees on Day 1 and Day 2. Dinesh (D) planted a Mango tree on Day 1. Therefore, A and D could not have planted Orange trees on all the three days. Farhan (F) could not have planted Orange trees on all the three days as only 1 Orange tree was planted on Day 2, while he had planted 2 trees on Day 2. Therefore, only Ekant (E) is left who must have planted 1 Orange tree on Day 3 and also planted Orange trees on Day 1 and Day2.

Exactly two people out of A, D and F planted the same type of tree on all the three days; the possible person-tree combinations in such a case could be: A-Coconut, D-Mango, F-Guava. Exactly 2 out of the given 3 combinations are true. On Day 3, they definitely planted these types only, as otherwise the given condition could not be true. So A is definitely one of the persons who planted the same type of tree on all the three days.

On Day 2, D did not plant Apple, Banana, Coconut or Orange tree. D could not have planted a Guava tree on Day 2 as in that case even F would not be able to plant Guava trees on all the three days. Therefore D must have planted 1 Mango tree on Day 2. Therefore, D is the other person to have planted the same type of tree on all the three days.

Name Day 1 Day 2 Day 3
Ashish 4 (Coconut) 4 (Coconut) 1 (Coconut)
Bobby 2 1 2 (Orange)
Chetan 2 1 4 (Orange)
Dinesh  1 (Mango) 1 (Mango) 1 (Mango)
Ekant 2 (Orange) 1 (Orange)  1 (Orange)
Farhan 2 2 1 (Guava)

 

95. (b)

96. (a)

97. (d) From Statement A:
Some of the cases possible according to Statement A are given below (left to right in the decreasing order of ages):

1. Steven Frank Wayne Lampard Rooney Gerrard

2. Steven Frank Wayne Rooney Lampard Gerrard

3. Steven Frank Rooney Wayne Gerrard Lampard 

Clearly, Statement A is insufficient to find who is the youngest among the 6 brothers.

From Statement B:

The following are the only two possibilities for the correct order of the decreasing ages (left to right) for the brothers which can be derived from Statement B:

1. Steven ______ Gerrard Wayne _______ _______
2. Steven Gerrard ______ _______ Wayne ______

The exact place for Frank, Lampard and Rooney cannot be decided in the above two arrangements.

Combining Statement A and Statement B:

The only possible order (left to right in the decreasing order of ages) is:

Steven Gerrard Frank Rooney Wayne Lampard So Lampard is the youngest. Hence, the question can be answered by using both the statements together, but cannot be answered by using either statement alone.

98.(d)  If James arrived before Lars then following possibilities exist (left to right in the order of arrival):

1. James, Lars, ______, _______

2. James, ______, Lars, _______

3. James, ______, ______, Lars (this possibility  gives no arrangement)

4. ______, James, Lars, ______

5. ______, James, _______, Lars

6. ______, _______, James, Lars (this possibility  gives no arrangement)

The only arrangements possible for the order of their arrival are:

I. James, Lars, Cliff, Dave (from 1)

II. James, Lars, Dave, Cliff (from 1)

III. James, Cliff, Lars, Dave (from 2)

IV. Cliff, James, Lars, Dave (from 4)

V. Cliff, James, Dave, Lars (from 5)

From the above 5 possible arrangements it is evident that Dave could never be the 2nd friend to arrive.

99.(d) Case 1: Kurt and Cobain lie.

This is not possible as then according to Kurt’s statement Cobain must speak the truth.

Case 2: Cobain and Morrison lie.

This is possible.

Case 3: Kurt and Jim lie. 

This is possible.

100. (b) The following arrangement is possible 

S R T P Q V

There are exactly 3 people between R and V.

How to prepare for Data Interpretation and Logical Reasoning (DILR) in CAT Exam?

The preparation for Common Admission Test starts in 1 year. Since DI-LR is one of the difficult sections, daily practice is needed. The preparation strategy needs to be on point and candidate should spend a good amount of time strengthening their concepts.

Following are the points, which will help in the preparation of DILR:

  • Practice 1 Data Interpretation and Logical Reasoning (DILR) set daily.
  • Practice sectional mock every 10 days.Doing mock tests every single day will help improve speed and accuracy, which is very necessary while solving this section in the actual CAT exam.
  • Calculating percentage changes or comparing ratios is a time-saving skill.
  • Attempting questions that you can confidently answer in 2 to 2.5 minutes would prove to be a better idea.Time Management is of utmost importance when it comes to this section, as one should not be sitting with the same questions for hours together. Move on if you’re not sure of the answer, and come back to it towards the end of the test. This way you will be confident of what you have already answered and there will be no panic.
  • Ration the time between Quant and DI section would help all neither neglect nor spend excessive time on any of these areas.
  • Start with an easy set followed by a medium and finally a difficult one.
