If 9 = 63, 8 = 48, 7 = 35 Then 4 = ?

Question

If 9 = 63,
8 = 48,
7 = 35
Then 4 = ?

A. 8

B. 6

C. 16

D. 12

Answer: A. 8

Solution:

Here given that 9 = 63, 8 = 48, 7=35, …

The given question follows a pattern that

9 x (9 – 2) = 9 x 7 = 63

8 x (8 – 2) = 8 x 6 = 48

7 x (7 – 2) = 7 x 5 = 35

Similarly, 4 x (4 – 2) = 4 x 2 = 8.

Hence, the answer is 8.
