What is Data Interpretation for CAT Exam
Data Interpretation is one of the most significant elements of the CAT exam.
Off late CAT as changed gears for DI and within this context, you might find lesser pie charts and bar charts in this section whereas you will get data in text format more than pie charts or bar graphs.
The above has been done to test your analytical skills better than before. For DI, you must have clarity on data interpretation. This skill over here in DI section is how you approach towards data and how you are able to respond to data in a given situation.
It is pertinent to note that in DI section, it is your observation to dig out the relevant data and that will be helpful for you to interpret the correct answer.

Solutions
Question-1 Answer-(C) Solution:
Givenratio of Incomes is 3 :1 Ratio of savings = 5 :7
Let the total savings be Rs .12
Investments In PPF = 30% of total savings
30% of 12 = 3.6
Required percentage:
={3.65)x20
= 72%
Question-2 Answer-{B) Solution:
Taxes constitute 18% of Mr.TAPA N's income andrate of tax is 30% beyond 1lakh.
=H8% ofIncome = 30% of {Income - one lakh) '* 30000 = 12% ofIncome
'*Income= Rs .2.5 lakh Similarly,for Mrs .TAPAN
10% of income = 20% of {Income - one lakh) '* 10% of income = 20000
'*Income = Rs .2 lakh Ratio of earnings = 5 : 4
Question-3
U sing similar logic as above we will answer -(D)
Question-4 Answer -(B) Solution :
From the bar - graph we get to know that the number of competitors of Cl, C2, C3, C4, CS, C7 and CS is l, 3, 6, 4, 7, 3 and 6 respectively.Since CS is the competitor of each of the other companies,therefore the only competitor of Cl is CS.let's consider C3:Number of competitors is 6.We know for sure that Cl is not the competitor of C3; therefore the six competitors of C3 are C2, C4, CS, C6, C7 and CS .Similarly CS:Number of competitors is 6 and the competitors of CS are C2, C3, C4, CS, C6 and C7.Therefore competitors of C7 are CS, C3 and CS and competitors of C2 are CS, C3 and CS.
Since the competitors of Cl, C2, C3, CS, C7 and CS are known and fixed by us, the third competitor has to be C6.Therefore the competitors of C6 are CS, C3, CS and C4. Now consider C4 :Out of the four competitors it has, three are CS, C3 and CS .So number of competitors of C6 is 4
Question-5 Answer-(E) Solution:
From the bar - graph we get to know that the number of competitors of Cl,C2,C3,C4,CS,C7 and CS is 1,3,6,4,7,3 and 6 respectively. Since CS is the competitor of each of the other companies, therefore the only competitor of Cl is CS .
Let's consider C3 : Number of competitors is 6.We know for sure that Cl is not the competitor of C3; therefore the six competitors of C3 are C2,C4,CS,C6,C7 and CS. Similarly CS:Number of competitors is 6 and the competitors of CS are C2,C3,C4,CS,C6 and C7.
Therefore competitors of C7 are C5,C3 and CS and competitors of C2 are CS,C3 and CS .Since the competitors of Cl,C2,C3,C5,C7 and CS are known and fixed by us,the third competitor has to be C6.Therefore the competitors of C6 are CS,C3,CS and C4.
Now consider C4 :Out of the four competitors it has, three are CS,C3 and CS .Since the number of competitors of Cl,C2 and C7 is ,3 and 3 respectively,therefore the numberof competitors who sell furniture in the regions in which either of Cl,C2 and C7 sell furniture canbe at most 4.So the region in which maximum possible numbers of competitors sell furniture is the one that sells C4 or C6.So,such a region could possibly have CS,C4,C6,C3 and CS .Hence at most 5 competitors can sell furniture in one region.
Question-6 Answer-(C) Solution:
From the bar - graph we get to know that the number of competitors of Cl, C2, C3, C4, CS, C7 and CS is
l, 3, 6, 4, 7, 3 and 6 respectively.Since CS is the competitor of each of the other companies, therefore the only competitor of Cl is CS.
Let's consider C3:Number of competitors is 6.We know for sure that Cl is not the competitor of C3; therefore the six competitors of C3 are C2, C4, CS, C6, C7 and CS.
Similarly CS: Number of competitors is 6 and the competitors of CS are C2, C3, C4, CS, C6 and C7. Therefore competitors of C7 are CS, C3 and CS and competitors of C2 are CS, C3 and CS .Since the competitors of Cl, C2, C3, CS, C7 and CS are known and fixed by us,the third competitor has to be C6.
Therefore the competitors of C6 are CS, C3, CS and C4.Now consider C4 : Out of the four competitors it has,three are CS, C3 and CS .Hence the number of regions in which Cl sells furniture is at most 2.
Question-7
Answer -{A) Solution :
Percentage change (rise/fall) in the production of Company Y in comparison to the previous year, for different years are:
For 2010 =({35-25)/25x100)% = 40%.
For 2011 =({35-35)/25x100)% = 0%.
For 2012 =({40-35)/35x100)% = 14.29%.
For 2013 =({50-40)/40x100)% = 25%.
Hence, the maximum percentage rise/fallin the production of Company JK ltd is for 2010
Question-8
Answer-(C)
Question-9 Answer-{B) Solution:
Required difference:
=({45-25)x ,00,000) tons
= 20,00.000 tons
Question-10
Answer-(D)
Ouestion-11 Answer-(B) Solution:
The required percentage:
=5350+7215/2600+1070+5350+7215+2400+1440+2110+1840+1900+3880+3315
= 38%
