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)
  1. The age gap never changes: 45−24=2145 - 24 = 21 years.
  2. When Ike is half his father's age, the father is twice Ike's age, so the gap equals Ike's age.
  3. Ike was 21 and his father 42.
  4. Ike was 21 three years before 1984 (when he was 24), so the year was 1981, option B.
