Jar X is 1/2 full of water. Jar Y, which has half the capacity of Jar X, is 1/4 full of water. If the water in Jar Y is poured into Jar X, then Jar X will be filled to what fraction of its capacity?  Choose the correct choice from the following:
A) 3/4 B) 5/8 C) 7/8 D) 5/12 E) 7/12
Let P be the capacity of Jar X.   The amount of water in Jar Y is 1/4*P/2=P/8   Then the total amount in Jar X is P/2+P/8=5P/8   The answer is 5/8.
