*Important Formulas on "Problems on Ages" :*

1. If the current age is *x*, then *n* times the age is *nx*.

2. If the current age is *x*, then age *n* years later/hence = *x* + *n*.

3. If the current age is *x*, then age *n* years ago = *x* - *n*.

4. The ages in a ratio *a* : *b* will be *ax* and *bx*.

5. If the current age is x, then |
1 | of the age is | x |
