Question 52
The ages of Khushi and jagriti are in the ratio 5 : 8. After 8 years the the ratio of their ages will be 3 : 4. What is the difference in their ages ?
Solution
Let their ages be 5x and 8x. After 8 years, their ages are 5x + 8 and 8x + 8. But 5x+8:8x+8 = 3:4
Solving for x, we get x = 2
So, difference of ages = 8x - 5x = 3x = 6 years
