John, Ahmad, Luis and Carl shared $100. Carl received ²₃ of the total amount of money received by John, Ahmad and Luis. John received ¹₄ of the total amount for Ahmad and Luis. Ahmad received ¹₂ as much money as Luis. If Ahmad gave all his money to Carl, how much did Carl have more than John in the end?

John	Ahmad	Luis	Carl	Total
3x5			2x5	5x5
1x3	4x3
	1x4	2x4
3 u	4 u	8 u	10 u	25 u

The total amount that Ahmad and Luis have is repeated.  Make the total amount of Ahmad and Luis the same.  LCM of 3 and 4 is 12.

The total amount that John, Ahmad and Luis have is repeated.  Make the total amount of John, Ahmad and Luis the same. LCM of 15 and 3 is 15.

Total amount that John, Ahmad, Luis and Carl shared = 25 u

25 u = 100

1 u = 100 ÷ 25 = 4

	John	Ahmad	Luis	Carl
Before	3 u	4 u	8 u	10 u
Change		- 4 u		+ 4 u
After	3 u	0 u	8 u	14 u

Amount that Carl had if Ahmad gave him all his money
= 10 u + 4 u
= 14 u

Amount that Carl had more than John
= 14 u - 3 u
= 11 u
= 11 x 4
= $44

Answer(s): $44
