If X, Y > 0, what is the value of 5XY2?

(1) 4XY2 = 9X3Y5/XY
(2) X, Y are both prime numbers.

 
you can get the answer from any one of the statements
you can get the answer from both the statements
you can get the answer from (1) and (2) together, although neither statement by itself suffices
you cannot get the answer from statements (1) and (2) together, but need even more data
