Question

Choose the correct answer from the alternatives given.
The sum of the digits of a number A is $13$. What is the remainder when A is divided by $3$?

Answer 1

Since the sum of the digits is 13, the number when divided by 3 leaves remainder 1.

Because if the sum of the digits would have been 12 then it would have been divisible by 3.

Since 13 is 1 bigger than 12, remainder will be 1 when divided by 3.
