The sum of ages of a father and his son is 56 years. After 4 years, the age of the father will be three times that of the son. What is the current age of the father?
Answer and explanation
Correct answer: A. 44 years
- Step 1: F + S = 56.
- Step 2: In 4 years: (F + 4) = 3(S + 4) => F + 4 = 3S + 12 => F - 3S = 8.
- Step 3: Subtract (F - 3S = 8) from (F + S = 56): 4S = 48 => S = 12 years.
- Step 4: Father's current age F = 56 - 12 = 44 years.
