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