## 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.**
