1. 2 and 2
2. 2 and 0
3. 0 and 2
4. 0 and 0

Answer 1

Correct Answer - Option 3 : 0 and 2

Given:

The number is 23M5N,

Concept:

A number is divisible by 12 if the number formed by the last two digits in the number is divisible by 4 and the sum of the digit in the number is divisible by 3.

Calculation:

⇒ If we will put 0 and 2 in the place of M and N respectively. than both conditions will be satisfied.

∴ The required result will be 0 and 2.
