**Q11. The age of a man is 3 times that of his son. 15 years ago, the man was 9 times as old as his son. What will be the age of the man after 15 years ?**

45 years

60 years

75 years

65 years

50 years

Solution:

Let age of Man = 3x

Age of son = x

According to question,

3x - 15 = (x - 15) 9

⇒3x - 15 = 9x - 135

∴ x = 120/6 = 20 years

∴ Required answer = 20 × 3 + 15 = 75 years.

Age of son = x

According to question,

3x - 15 = (x - 15) 9

⇒3x - 15 = 9x - 135

∴ x = 120/6 = 20 years

∴ Required answer = 20 × 3 + 15 = 75 years.
