Question
Six years from now, Kirti's age will be twice that of
her brother Kunal, but 4 years ago she was three times as old as Kunal was then. Find the present age of Kunal.Solution
Let the present age of Kirti =x and Kunal =y ATQ- After 6 years- X+6 = 2(y+6)          … (1) Before 3 years – x-4 = 3(y-4) x-4 =3y-12 x =3y-8        …. (2) put the value of x in Eq (1) 3y -8+6 =2y+12 3y -2 =2y+12 y =14 years.
