The present ages of A and B are in the ratio 5 : 6 respectively. After seven years this ratio becomes 6 : 7. Then the present age of A in years is :
-
- 35 years
- 32 years
- 33 years
- 30 years
Correct Option: A
A’s present age = 5x years
B’s present age = 6x years
According to the question,
After 7 years,
| = | ||
| 6x + 7 | 7 |
⇒ 36x + 42 = 35x + 49
⇒ 36x – 35x = 49 – 42
⇒ x = 7
A’s present age = 5x = 35 years
