1. The sum of the present ages of a father and his son is 60 years . Six years ago, father's age was five times the age of the son. After 6 years, son's age will be -
- A. 12 years
- B. 12 years
- C. 12 years
- D. 12 years
Answer: Option D
Explanation:
Let the present ages of son and father be x and (60 - x) years respectively.
Then, (60 - x) - 6 = 5(x - 6)
⇒ 54 - x = 5x - 30
⇒ 6x = 84
⇒ x = 14
∴ Son's age after 6 years = (x + 6) = 20 years.
Then, (60 - x) - 6 = 5(x - 6)
⇒ 54 - x = 5x - 30
⇒ 6x = 84
⇒ x = 14
∴ Son's age after 6 years = (x + 6) = 20 years.
