Question

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

Answer 1

22.

Explanation:

We can rewrite the question as these equations:

Mother's age: `x`

Sarah's age: `x-24`

Both: `x+x-24=68`

So: `2x=92`

Therefore: `x=46` (Which is the Mother's age)

We then substitute `x` back into Sarah's age: `46-24=22`
