If a number is divided by 5, remainder is 2. What should be the last digit of the number?


2 or 7

Step by Step Explanation:
  1. This solution can be explained by an example.
    If 12 is divided by 5, the remainder is 2. If 17 is divided by 5 then the remainder is also 2.
  2. So the last digit could be 2 or 7.
  3. A simple way of remembering it is that the last digit when a number is divided by 5 could be the remainder itself (2) or the 5 + remainder(7).
