John was 22 years old when he married Betty. They just celebrated their fifth wedding anniversary, and Betty's age is now 7/9 of John's. How old is Betty?	Choose the correct option
A) 24 B) 26 C) 28 D) 21 E) 32
Assume Betty's age on marriage = x years.   John's age on marriage = 22   John's age after 5 years = 27 years.   Betty's age after 5 years = x + 5   Given: x + 5 = 7/9 (27) = 21   Therefore Betty's current age = 21   Option 21
