Q. What is the final output?

A.12

B.21

C.11

D.15

E. None of these

Ans: 11

Sol:

We have:
For step I: the average of the digits is taken.
(8 + 4)/2 = 6 and (3 + 5)/2 = 4
For step II: (6 x 4) + 5 = 29 and (5 x 3) + 7 =
22
For step III: Difference between the sum of the
square of the digits are taken.
(2² + 9²) – (2² + 2²) = 77

Based on the step followed above we have the
final output for the given input:
