John was 22 years old when he married Betty.
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?
Answer/Solution
21
Steps/Work
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 D
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 D
