Five years ago, the ratio of the ages of Tarun and Saurabh was 4 : 1. After five years, the ratio of their ages will be 2 : 1. What is the present age (in years) of Saurabh?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 10.
Let the present age of Tarun = x years
And the present age of Saurabh = y years
According to the question;
Five years ago, the ratio of the ages of Tarun and Saurabh was 4: 1
⇒ (x - 5)/(y - 5) = 4/1
After five years, the ratio of their ages will be 2: 1
⇒ (x + 5)/(y + 5) = 2/1
Solving both equations;
The present age of Tarun = 25 years
And the present age of Saurabh = 10 years
