Question

P and Q are two integers such that PQ = 64. Which of the following cannot be the value of P+Q? (CAT 1997)

• A. 20
• B. 65
• C. 16
• D. 35

Answer 1

The correct option is D 35

P$\times$Q = 64 = 1 $\times$ 64 = 2 $\times$ 32 = 4 $\times$ 16 = 8 $\times$ 8.

Corresponding values of P + Q are 65, 34, 20, 16.

Therefore, P + Q cannot be equal to 35.
