The current ages of Sudhir and Ashish are in the ratio 5 : 7. Twelve years ago, the ratio of their ages was 1 : 2. What will be the age of Sudhir five years from now?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 25 years.
Let the current ages of Sudhir and Ashish be 5x and 7x
Twelve years ago, the ratio of their ages was 1 : 2
According to the question
⇒ (5x - 12)/(7x - 12) = 1/2
⇒ 10x - 24 = 7x - 12
⇒ 3x = 12
⇒ x = 12/3
⇒ x = 4
So, the current ages of Sudhir is 5x = 5 × 4 = 20
Hence,
The age of Sudhir after five years from now = 20 + 5 = 25 years
