Correct Answer - Option 3 : 4
Given:
An 8- digit number: 4252746B
Remainder = 0 when divided by 3
Calculation:
As per the divisibility tests, the sum of all the digits of the number should be divisible by 3
So,
4 + 2 + 5 + 2 + 7 + 4 + 6 + B
= 30 + B
30 is completely divisible by 3. So, for remainder 0, the possible values are 0, 3, 6, 9.
∴ The number of possible values of B is 4
