Who wants to have a little algebra fun? OK here we go:
The sum of the ages of Mary and Ann is 44. Mary is twice as old as Ann was when Mary was half as old as Ann will be when she is three times as old as Mary was when she was three times as old as Ann. How old are Mary and Ann?
My high school maths teacher took about 2 or 3 minutes to solve this when I presented it to him. It took me about 3 hours! (I never was a good student). If you get fed up, I'll post the answers here in a few days. I won't show the working out because it takes a while. And yes, it's possible to do without a calculator. If you'd like a clue read on:
It helps if you work through it backwards.
