Question
The ratio of the ages of Sneha, Ritu, and Anjali is
3:4:5 respectively. Meera is 6 years younger than Ritu. If the difference between Anjali and Sneha’s age is 24 years, what is the ratio of Ritu’s age to Meera’s age?Solution
Let their ages be 3x, 4x, and 5x respectively.Â
So, Meera’s age = (4x - 6)
ATQ,Â
5x - 3x = 24Â
Or, 2x = 24Â
Or, x = 12
So, Ritu’s age = 4 × 12 = 48Â
And, Meera’s age = 48 - 6 = 42
Required ratio = 48:42 = 8:7Â Â
