Dan is 14 years older than Marge. Eight years ago, Dan was three times as old as Marge. How old is Dan?

Dan is 25 years old.

Step-by-step explanation:

1. Find out Dan's age from 8 years ago: 14 - 8 = 6

2. Find out how old Marge was: 6 : 2 = 3

3. Add 8 years to Marge's age to find out how old she is now: 3 + 8 = 11

4. Add 14 years to Marge's age now to find out Dan's age now: 11 + 14 = 25

∴ Dan is 25 years old

Dan is 25 years old, that should be the answer
