The ages of X and Y are in the ratio of 3:8 respectively and product of their ages is 384. Compute the ratio of their ages three years hence.
a.3:5
b.2:5
c.3:7
d.3:4

• as given the ages are of 3x,8x and product of their ages is 384
  so, 3x*8x=384
  by solving we get 24x^2=384
  finally by sloving we get x^2=16
  x=4
  as given three hence we add 3 for 3x and 4x
  we solve it by
  3x+4:8x+4
  sub x=4 in above ration
  we get
  15:35
  3:7
  is it correct

• 3:7
  3x*8x=384
  =>x=4
  3x+3:8x+3=15:35

• x,y are in the ratio 3:8 so,
  3x,4x
  3x*8x=384,
  24x^2=384
  x=4,
  then 3x=12,8x=32,
  after 3 years,15,35
  in ratio 15:35=3:7
