Question

At present the age of riya's mom is seven times the age of riya ten years hence the age of the mother will be three times the age of riya find their present ages

Answer 1

Step-by-step explanation:

let the age of Riya=x

Riya's mom is seven times the age of Riya=7x

after 10 yr her mother will be 3 yr age of riya=3x.

than,

x+7x=10+3x

8x=10+3x

8x-3x=10

5x=10

x=10/5

x=2

therefore the age of Riya is 2 years.

and the age of her mother is 7x

i.e. 7(2)=14 yrs.

after

10yrs=14+10=24yrs

Answer 2

Step-by-step explanation:

let riyas present age be x

riyas mother present age will be 7x

10 years later

riyas age will be x + 10

mother age will be 7x + 10

3(x + 10) = 7x + 10

3x + 30 = 7x + 10

30 - 10 = 7x - 3x

4x = 20

x = 20/4

x = 5

riyas present age is = x = 5

mother age = 7x = 7 × 5 = 35

hope you get your answer
