Question

Q5: Sunita is 3 times as old as her little brother Rakesh. But in 3 years, she will be twice as old as
Rakesh will be then. Find their present ages.
​

Answer 1

Answer:

Rakesh's current age = 3 years

Sunita's current age =  9 years

Step-by-step explanation:

Let Rakesh's current age in years = x

=> Sunita's current age in years = 3x

After 3 years

Sunita's age in years = 3x + 3

Rakesh's age in years = x + 3

Given: Sunita will be twice as old as Rakesh

=> 3x + 3 = 2(x + 3)

=> 3x + 3= 2x+ 6

=> 3x - 2x = 6 - 3

=> x = 3

Rakesh's current age = x = 3 years

Sunita's current age = 3x = 9 years

Verification:

After 3 years, Sunita will be 12 which is twice of Rakesh's age at that time (6)
