In 1984, Ike was 24 years old and his father was 45 years old. In what year was Ike exactly half his father's age?
Worked solution (try it first)
- The age gap never changes: years.
- When Ike is half his father's age, the father is twice Ike's age, so the gap equals Ike's age.
- Ike was 21 and his father 42.
- Ike was 21 three years before 1984 (when he was 24), so the year was 1981, option B.
