The present ages of Ramu and Ravi are in the ratio of 4 : 3. After 5 years, the ratio of their ages will be 5 : 4. Find their present ages, respectively.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 20 years, 15 years.
Let present ages of Ramu = 4x and Ravi = 3x
(4x + 5)/(3x + 5) = 5/4
⇒ 16x + 20 = 15x + 25
⇒ x = 5
Ramu = 4 × 5 = 20 years
Ravi = 3 × 5 = 15 years
