Question

From the given options, choose the number which when added to 987655 will make the resultant number divisible by 3.

• A. 0.0
• B. 1
• C. 2
• D. 3

Answer 1

The correct option is C 2

A number is divisible by 3 if the sum of its digits is divisible by 3.

Sum of digits of 987655 = 40 and 40 is not divisible by 3.

If we add 0, 1 and 3 to 987655, the resultant sum of digits will be = 40, 41 and 43 respectively. None of these are divisible by 3.

If we add 2 to 987655, the resultant number will be = 987657 and sum of the digits will be 42 which is divisible by 3.
Hence, the number that should be added to 987655 to make it divisible by 3 is 2.
