Dianne is 23 years older than her daughter Amy. In 6 years Dianne will be twice as old as Amy. How old are they now?

Answer 1

Let x = Amy's age now

Then, x+23 = Diane's age now

Diane's age in 6 years = 2(Amy's age in 6 years)

So, (x+23) + 6 = 2(x+6)

x + 29 = 2x + 12

x = 17

Amy is 17 and her mother is 40.
