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?

  ml

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
