Question

the present age of Rahul is the thrice that of his brother. Six years hence, their ages will be in the ratio 9:5. Find their percent age​

Answer 1

Answer:

Rahul 12 years , his brother 4 years

Step-by-step explanation:

Let Rahul's brother's age is x years

So, Rahul's age is 3x years

After 6 years,

Rahul's brother's age is x+6 years

and Rahul's age is 3x+6

Given ratio is 9:5

so, (3x+6)/(x+6) = 9/5

Or, 15x + 30 = 9x+54

Or, 6x = 24

Or, x = 4

Or, 3x = 12
