Tommy, Paul, Fred and Oscar shared $210. Oscar received ¹₄ of the total amount of money received by Tommy, Paul and Fred. Tommy received ³₅ of the total amount for Paul and Fred. Paul received ¹₂ as much money as Fred. If Paul gave all his money to Oscar, how much did Oscar have more than Tommy in the end?

Tommy	Paul	Fred	Oscar	Total
4x6			1x6	5x6
3x3	5x3
	1x5	2x5
9 u	5 u	10 u	6 u	30 u

The total amount that Paul and Fred have is repeated.  Make the total amount of Paul and Fred the same.  LCM of 3 and 5 is 15.

The total amount that Tommy, Paul and Fred have is repeated.  Make the total amount of Tommy, Paul and Fred the same. LCM of 24 and 4 is 24.

Total amount that Tommy, Paul, Fred and Oscar shared = 30 u

30 u = 210

1 u = 210 ÷ 30 = 7

	Tommy	Paul	Fred	Oscar
Before	9 u	5 u	10 u	6 u
Change		- 5 u		+ 5 u
After	9 u	0 u	10 u	11 u

Amount that Oscar had if Paul gave him all his money
= 6 u + 5 u
= 11 u

Amount that Oscar had more than Tommy
= 11 u - 9 u
= 2 u
= 2 x 7
= $14

Answer(s): $14
