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.  Choose the correct choice from the following.
A) 3:5
B) 2:5
C) 3:7
D) 3:4
E) 1:4
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   ANSWER:3:7
