Question

If Sarah is 24 years younger than her mother and if the sum of their ages is 68, how old is Sarah?

Answer 1

22 years

Explanation:

let mothers age be x and sarah's age be y

`x-y=24` ...................(i)
`x+y=68` ................(ii)

adding (i) and (ii)

`2x=92`
`x=46`

Therefore mother's age=46
Hence Sarah's age=22
