Question

Ruby’s grandmother’s age is 15 times more than Ruby’s age. After 10 years, Ruby’s grandmother will

be 5 times as old as Ruby. Find their present ages.​

Answer 1

Answer:

Let the age of Rudy = x.

Grandmothers age = 15x.

After 10 years it will be :

Rudy = (x+ 10) years

Grandma = (15x+10) years

On solving both equations, we get :

= 15x+10 = 5(x+10)

= 15x-5x = 40

 x = 4

Rudy's age = 4

Her grandmother's age = 4 * 15  = 60.

Answer 2

Let the age of rudy = x.

Grandmothers age = 15x.

After 10 years it will be :

Rudy = (x+ 10) years

Grandma = (15x+10) years

On solving both equations, we get :

= 15x+10 = 5(x+10)

= 15x-5x = 40

x = 4

Rudys age = 4

Her grandmother's age = 4 * 15

= 60.
