Question

If $N÷5$ leaves a remainder of 3, what might be the ones digit of the number N?

• A. Either 6 or 9
• B. Either 2 or 1
• C. Either 7 or 2
• D. Either 3 or 8

Answer 1

The correct option is D

Either 3 or 8

A number which is divisible by 5 has either 0 or 5 in it ones place.

Since, the number N leaves 3 as the remainder when divided by 5, the last digit can be (0 + 3 = 3) or (5 + 3 = 8) .

So, the last digit or the ones digit of the number which leaves 3 as a remainder is either 3 or 8.
