three times his age. How old are they at present?
Years
Rohan's age
Years
Grandmother's age​

Answer 1

Answer:

grandmother age = x

Rohan's age = y

now , x=5y

and , 3(y+10)=x+10

hence , 3y+30 =x +10

=> 3y +20 = 5y

=> 2y = 20

=> y = 10

Rohan's age = 10 yr

gm's age = 50 yr

mark me brainliest
