Question

This year on his birthday, John will be two years older than three times Sue's current age. If the sum of their ages will be 74 on John's birthday, how old is Sue now?

Answer 1

If John is 2 years older, subtract 2 from 72.  That's 3 times Sue's current age.  Then divide 72 by 3.  72/3=24.  So Sue is 24
