If the product 4864 x 9 P 2 is divisible by 12, then the value of P is:

### Answer & Explanation:

Answer: Option E

Explanation: Clearly, 4864 is divisible by 4.

So, 9P2 must be divisible by 3.

So, (9 + P + 2) must be divisible by 3.

P = 1.

-84 x 29 + 365 = ?

### Answer & Explanation:

Answer: Option D

If the number 97215 * 6 is completely divisible by 11, then the smallest whole number in place of * will be:

### Answer & Explanation:

Answer: Option A

Explanation: Given number = 97215x6

(6 + 5 + 2 + 9) - (x + 1 + 7) = (14 - x), which must be divisible by 11.

x = 3

If the number 5 * 2 is divisible by 6, then * = ?

### Answer & Explanation:

Answer: Option A
