here is the question:-

The ages of Arun and Rahul are in the ratio 7:5. Ten years hence, the ratio of their ages will be 9:7(not 19:17). Find their present ages.

Thanks, guys

Answer 1

Let Arun’s and Rahul’s age be 7x and 5x respectively.

After 10 yrs, their ages are 7x + 10, 5x + 10 respectively.

As per the given condition, Ratio after 10 years is 9:7

So,

Cross Multiplying, we get

7(7x + 10) = 9(5x + 10)

49x + 70 = 45x + 90

49x - 45x = 90 - 70

4x = 20

x = 5

Therefore,
Arun’s age = 7 × 5 = 35 years

Rahul’s age = 5 × 5 = 25 years

THEIR AGES ARE 35 AND 25
