Let present age of Rossini=x
Present age of rohit =2x
Five years ago age of roshini =x-5
Five years ago age of rohit =2x-5
2x-5=3(x-5)
2x-5=3x-15
10=x
Age of roshini =10
Age of rohit =20

Answer 2

Answer:rohit's age - 20 yrs

roshani's age - 10 yrs

Step-by-step explanation:

let us consider the age of roshani = x yrs

so rohit's age - 2x yrs

five years ago = roshani age= x-5 rohit's age = 2x-5

According to the question, 2x-5=3(x-5)

2x-5=3x-15

On transferring, we get -5+15=3x-2x

10 = x

so roshani age = 10 yrs

rohit's age = 20 yrs
