The ratio of the present ages of Radha and Saloni is 2 : 3. After 7 years, the ratio of their ages will be 3 : 4. If Radha is 7 years younger than Saloni, what is Radha’s present age (in years)?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 14
In the ratio 2 : 3 the ages differ by one part, and that difference is given as 7 years.
Radha \(=2k\), Saloni \(=3k\); \(3k-2k=7\), so \(k=7\)
Radha \(=14\) years, Saloni \(=21\) years
After 7 years: \(21:28=3:4\), as given
