Jar X is 1/5 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? Choose the most appropriate option:
A) 2/5  B) 3/5  C) 7/10  D) 7/20  E) 9/20
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/5+P/4=9/20   The answer is 9/20.
