**Slot -2 – Quantitative Aptitude – Number System – If the sum of squares of two numbers is 97**

**If the sum of squares of two numbers is 97, then which one of the following cannot be their product?**

a) −32

b) 16

c) 48

d) 64

Answer: d) 64

Solution: let numbers are a and b.

Given, a^2+b^2=97

Using A.M.≥G.M

(a^2+b^2)/2 ≥ (a^2 b^2 )^(1/2)=ab

ab ≤ 97/2 = 48.5

Thus product of numbers can not be greater than 48.5

Option d) 64 is correct
