Question

Riyas mom age was thrice the age of Riya .After 10 year's mom will be twice the age of her daughter Riya . Find the sum of their ages

Answer 1

Step-by-step explanation:

Let riya's age be x and mom's age be 3x

ATQ,

After 10 year's mom will be twice the age of riya

3x + 10 = 2( x + 10)

3x + 10 = 2x + 20

3x - 2x = 20 - 10

x = 10

putting the value of x in 3x we get,

3x = 3 × 10

= 30 years
