Ivan, Warren and Oscar shared a sum of money. The amount received by Warren was ⁵₆ the amount of money received by Oscar. After Ivan had given $51 to Warren and $21 to Oscar, Warren gave $4 to Oscar. In the end, 3 of them had the same amount of money. Find the difference between the amount of money that Ivan and Warren had at first.

	Ivan	Warren	Oscar
Before	5 u + 119	5 u	6 u
Change 1	- 51	+ 51
Change 2	- 21		+ 21
Change 3		- 4	+ 4
After	5 u + 47	5 u + 47	6 u + 25

Amount that Warren had in the end = 5 u + 47 

Amount that Oscar had in the end = 6 u + 25

Amount that Ivan had at first 
= 5 u + 47 + 51 + 21
= 5 u + 119

Amount that Warren and Oscar had in the end is the same.

5 u + 47 = 6 u + 25
6 u - 5 u = 47 - 25

1 u = 22

Amount that Ivan and Warren had in the end is the same.

Amount that Ivan had in the end
= 5 u + 47
= 5 x 22 + 47
= 110 + 47
= $157

Amount that Ivan had at first
= 157 + 51 + 21
= $229

Difference in the amounts between Ivan and Warren at first
= 229 - 110
= $119

Answer(s): $119
