Question

If P and Q are two positive integers such that PQ = 64, then which of the following cannot be the value of P + Q? 20,16,35,65​

Answer 1

Answer:

35

Step-by-step explanation:

64 can be written as

1*64 = 64 where 64+1 = 65

2*32 = 64 where 2+32 = 34

4*16 = 34 where 4+16 = 20

8*8 = 64 where 8+8 = 16

Hence we can find that 35 will not come as the sum of P and Q
