Two years ago man's age was three times the square of his son's age.Three years hence his age will be four times his son's age.What are their present? ages.

• ans Man age 29 and son age 5.
  according to question
  x=Man, y=son then 2 year ago (x-2)=3(y-2)^2
  3 year hence (x+3)=4(y+3)
  by sloving this equation we get 3y^2-16y+5=0
  and roots of equation y = 5 and 13 (which is not possible).
  then y=5 put this value in equation we get x=29.
