Question

If the division N÷5 leaves a remainder of 1, what might be the ones digit of N?

Answer 1

Solution:

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

Since, the number N leaves 1 as the remainder when divided by 5, the last digit can be (0 + 1 = 1) or (5 + 1 = 6)

So, the last digit or the ones digit of the number which leaves 1 as a remainder is either 1 or 6.
