Answer:
Let the age of son be x
Age of Father = 4x
4 years hence,
Age of son = x + 4
Age of Father = 4x + 4
According to question,
Age of Father after 4 years + Age of Son after 4 years = 43
⇒ 4x + 4 + x + 4 = 43
⇒ 5x + 8 = 43
⇒ 5x = 43 - 8
⇒ 5x = 35
⇒ x = 35 ÷ 5
⇒ x = 7
So, Age of son = x = 7 years
Age of Father = 4x = 4 × 7 = 28 years
Hence, 7 and 28 years is the correct answer.
