Chances are high that CAT 2014 might give surprises in QA. Over the years the pattern has shifted from pure calculation based questions to pure logic based ones. So, handle the questions accordingly and ensure a proper balance between attempt and accuracy.
CAT 2014 is being conducted on 16th & 22nd November 2014 this year. Practice with following Question and answer with solution:
Question: There are two concentric circles of radii 7 cm and 8 cm. PQ, a diameter of the larger circle, cuts the smaller circle at S and T. A tangent drawn from Q touches the inner circle at R. What is the length of PR (in cm)?
