Question

Rohan grandmother is five times his age after 10 years from now his grandmother will be 3 times his age how old are they at present​

Answer 1

suppose Rohan's grandmother's age is y and Rohan's age is x. Then you get:

y=5x

y+10=3(x+10)

Substitute the first into the second,

5x+10=3x+30

which gives 2x=20 or x=10

Thus, Rohan's current age is 10 and his grandmother's current age is 50.

10 years from now, they will be 20 and 60 respectively.

Answer 2

Answer:

Rohan Current age is 10
