Let Seema's present age = x yrs
So, Gaurav present age = (31 - x) yrs
Now after 10 years :
Seema's age = (x + 10)
Gaurav's age = (41 - x)
According to question -
x + 10 / 41 - x = 8 / 9
Now by cross multiplication we get
9x + 90 = 328 - 8x
9x + 8x = 328 - 90
17x = 238
x = 238 / 17
x = 14
So, present age of Seema =14 years
Present age of Gaurav = (31 - 14) = 17 years
