John was 19 years old when he married Betty. They just celebrated their fifth wedding anniversary, and Betty's age is now 7/8 of John's. How old is Betty?
Choose the most appropriate option:
A) 21	B) 26	C) 28	D) 30	E) 32
Assume Betty's age on marriage = x years.   John's age on marriage = 19   John's age after 5 years = 24 years.   Betty's age after 5 years = x + 5   Given: x + 5 = 7/8 (24) = 21   Therefore Betty's current age = 21   Option 21
