Jar X is 1/4 full of water. Jar Y, which has half the capacity of Jar X, is 1/2 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? Pick one.
A) 2/5	B) 1/4	C) 1/3	D) 1/2	E) 2/3
Let P be the capacity of Jar X.   The amount of water in Jar Y is 1/2*P/2=P/4   Then the total amount in Jar X is P/4+P/4=P/2   The answer is 1/2.
