Question

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

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



​

Answer 1

Ans.1

Given number = 97215x6

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

  x = 3

Ans.2

6 = 3 x 2. Clearly, 5 * 2 is divisible by 2. Replace * by x.

Then, (5 + x + 2) must be divisible by 3. So, x = 2.

Answer 2
