Canister C is 1/2 full of water and canister D, which has twice the capacity of canister C, is 1/3 full of water. If the water in canister D is poured in canister C until canister C is completely full of water, canister D will still contain what fraction of its capacity of water?	Select the correct option:
A) 0	B) 1/36	C) 1/12	D) 1/6	E) 1/4
Say canister C has a capacity of 6 liters. It's half full, thus there can be poured 3 liters of water.   Canister B is 12 liters and there are 4 liters of water. We can pour 3 liters from D to C and 1 liter will still be left in D, which is 1/12 of its total capacity.   Answer: 1/12.
