• A. 3
• B. 9
• C. 5
• D. All of These

Answer 1

The correct option is C

5

The sum of the digits of 152875 = 1 + 5 + 2 + 8 + 7 + 5 = 28 which is neither a divisible by 3 nor 9.

The last digit of 152875 is 5 which is divisible by 5 since any number that ends with 0 or 5 is divisible by 5.

A number is divisible by 2 if its unit's digit is 0, 2, 4, 6 or 8. Since the unit's digit is 5, the number is not divisible by 2.
