Question

Ten years ago Vibha was four times as old as Amogha, Now she is only twice old as Amogha.
Find their ages.​

Answer 1

Answer: Amogha is 15 and Vibha is 30.

Answer 2

Step-by-step explanation:

let amogha's age be x

vibha's age be y

ATQ,

4(x-10) = y - 10

4x - 40 = y-10

4x- y = 30. (1) eq.

2x = y. (2) eq.

putting value of y from (2) in (1)

4x - 2x = 30

2x = 30

x = 15

putting this value in (2)

2(15) = y

30 = y

y = 30

so, their ages are 15 and 30
