Sample Problem

Container A, B and C each contained 3600 ml of water. 1450 ml of water from Container A was poured into Container C, and 2010 ml of water from Container B was poured into Container A. As a result, how much more water was there in Container A than in Container B?

Solution

Make a list to show the changes.

	Container A	Container B	Container C
	3600 ml	3600 ml	3600 ml
A to C	3600 - 1450 = 2150 ml	3600 ml	3600 + 1450 = 5050 ml
B to A	2150 + 2010 = 4160 ml	3600 - 2010 = 1590 ml	5050 ml

Thus, the difference between A and B: 4160 - 1590 = 2570 ml
