# Problem on Ages

In solving the problem related to ages, we come across three situations.

- Age some year ago/back
- Present Age
- Age some years hence/after

Always we consider the present age to be the base for finding out the past age or further age.

For example if the present age of a person is ‘Y’.

Age of the person after 10 year will be X+10.

Age of the person 10 year before would be x-10.

## Example :

Present age of John is ‘25’.

Age of John after 10 year will be 25+10=35

Age of John Before 10 year would 25-10=15
