Oscar, Tommy and John shared a sum of money. The amount received by Tommy was ²₃ the amount of money received by John. After Oscar had given $53 to Tommy and $25 to John, Tommy gave $6 to John. In the end, 3 of them had the same amount of money. Find the difference between the amount of money that Oscar and Tommy had at first.

	Oscar	Tommy	John
Before	2 u + 125	2 u	3 u
Change 1	- 53	+ 53
Change 2	- 25		+ 25
Change 3		- 6	+ 6
After	2 u + 47	2 u + 47	3 u + 31

Amount that Tommy had in the end = 2 u + 47 

Amount that John had in the end = 3 u + 31

Amount that Oscar had at first 
= 2 u + 47 + 53 + 25
= 2 u + 125

Amount that Tommy and John had in the end is the same.

2 u + 47 = 3 u + 31
3 u - 2 u = 47 - 31

1 u = 16

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

Amount that Oscar had in the end
= 2 u + 47
= 2 x 16 + 47
= 32 + 47
= $79

Amount that Oscar had at first
= 79 + 53 + 25
= $157

Difference in the amounts between Oscar and Tommy at first
= 157 - 32
= $125

Answer(s): $125
