• This is a question based on rules of divisibility.

• The rule of divisibility of 3 is that the sum of all the digits of the number should be divisible by 3. We have 4 + 2 + 5 + 2 + 7 + 4 + 6 + B = 30 + B which is completely divisible by three.

• So B can take value as 0, 3, 6, or 9. • Hence 4 values are possible for B.
