Explanation

15 years ago, Karan was 50-15=35, Anjali was 30-15=15, and Meera was 40-15=25. The ratio is 35:15:25, which simplifies to 7:3:5.

AI explanation

Fifteen years ago, Karan was 35 years old (50 - 15), Anjali was 15 years old (30 - 15), and Meera was 25 years old (40 - 15). The required ratio is their ages at that time, which is 35 : 15 : 25. Dividing all terms by their greatest common divisor of 5 gives the simplified ratio of 7 : 3 : 5.
