Two equally sized jugs full of water are each emptied into two separate unequally sized empty jugs, X and Y. Now, jug X is 1/5 full, while jug Y is 4/7 full. If water is poured from jug X into jug Y until jug Y is filled, what fraction of jug X then contains water?	Choose the correct choice from the following:
A) 0 B) 1/15 C) 2/15 D) 1/20 E) 2/10
Suppose the water in each jug is L liters   CX x (1/5) = L   CX = 5L liters   CX is capacity of X   CY x (4/7) = L   CY = 7L/4 liters   CY is capacity of Y   Now, Y is 7L/4 - L empty = 3L/4 empty   So, we can put only 3L/4 water in jug Y from Jug X   Jug X's remaining water = L - 3L/4 = L/4   Fraction of X which contains water = water / CX   = (L/4)/ 5L   = 1/20   Answer will be 1/20
