If the number 91876Y2 is completely divisible by 8, then the smallest whole number in place of "Y" will be:

• A. 1
• B. 3
• C. 4
• D. 2

Answer 1

The correct option is B

3

For a number to be divisible by 8, the last three digits must be divisible by 8.

Here, 6Y2 must be divisible by 8.

For Y = 3, 632 is divisible by 8.
Therefore, 3 is the smallest possible whole number for Y.
