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.
