Question #2de14

Answer 1

`18` years

Explanation:

Damien's present age `=157` years.
Sarah's present age `=17` years.

Let after `x` years Damien's age is `5times` Sarah's age
Damien's age after `x` years`=157+x`
Sarah's age after `x` years`=17+x`

Using the given conditions
`157+x=5xx(17+x)`
`=>157+x=85+5x`
`=>5x-x=157-85`
`=>4x=72`
`=>x=72/4=18` years
