In CAT quotient Number systems test 13 why values of P, Q, R are taken as 5, 7, 9 respectively. Why can't 7, 9, 11 be an answer?

Hi Shubham,

You are referring to the second question in this test: https://cracku.in/cat/quotient/cat-2016-free-number-systems-test-13

We know that Q = P + 2 and R = P +4
Further more, we know that 3*P + 3 = 2*R
Hence, 3P+3 = 2P + 8 or P = 5
