**Reiny**, Wednesday, December 28, 2011 at 9:34amSam's money --- x

Jane's money --- y

y/5 = x/3

3y = 5x

y = 5x/3

Adam's --- z

difference in amount of Sam and Jane = 5x/3 - x

= 2x/3

"The difference in their amount is 1/2 of Adam's money" ---> 2x/3 = (1/2)z

z = 4x/3

after give-away:

Adam has 4x/3 - 120

so 4x/3 - 120 = 2x/3

times 3

4x - 360 = 2x

2x = 360

x = 180

Sam has 180

Jane has 300

Adam has 240 , together they have 720
