Each of the following questions has a different figures with Question mark/s. Replace the question mark/s by choosing the correct response from amongst the alternatives given.

Options

A. 49
B. 29
C. 19
D. 39

Answer

D

Explanation

The pattern is as follows:
`W = P^2-Q^2, X=Q^2- S^2 , Y=R^2-S^2, Z= R^2 - P^2`

In the first figure, `3^2 -2^2 = 5, 2^2 -1^2 = 3, 6^2 - 1^2 = 35, 6^2 - 3^2 = 27`
So, in the second figure, `5^2 - 4^2 = 9, 4^2 - 2^2 = 12, 8^2 -2^2 = 60, 8^2 - 5^2 = 39`
Therefore, missing number = 39
