Mary has a full 8-quart container (Container A) of peanut oil. She wants to share half of the oil with her sister. She has another 2 empty containers (B and C) with the capacities: 5 quarts and 3 quarts. Can you, without weighing the containers, put 4 quarts of oil in container B with the least number of steps for her sister?

Life is a Game play it.

One quick solution -

(1) Take out 3 quarts of oil from A into C. A has 5 quarts left now.

(2) Transfer 3 quarts from C to B. Now B has 3, A has 5 and C has zero.

(3) Take out Another 3 quarts from A into C. A=2, B=3, and C=3 now.

(4) Transfer from C to B only till B is full. A=2, B=5 and C=1 ((3-2)) now.

(5) Empty B in A now. A=7, B=0 and C=1;

(6) Put C in B. A=7, B=1 and C=0;

(7) Take out 3 quarts from A to C. A=4, B=1 and C=3.

(8) Transfer C to B. A=4, B=4 and C=0.

Done! Shorter maybe.....
