The ratio of ages of two persons is 5 : 9 and the age of one of them is greater than the other by 40 years. The sum of their ages in year is
-
- 180
- 140
- 150
- 160
Correct Option: B
Age of first person = 5x years
Age of second person = 9x years
According to the question,
9x – 5x = 40 ⇒ 4x = 40
⇒ x = 10
∴ Sum of their ages
= 5x + 9x = 14x
= 14 × 10 = 140 years
