Zeph, Henry and Asher have some stickers. The ratios of their stickers are as follows:

Zeph : (Zeph + Henry + Asher) = 1 : 3
Henry : (Zeph + Asher) = 1 : 5

Asher has 18 stickers more than Henry. In the end, Asher gives away all he has to Henry and Zeph so that both Henry and Zeph end up with the same number of stickers, how many stickers has Henry received from Asher?

Henry	Asher	Zeph	Total
2x2		1x2	3x2
1x1	5x1		6x1
1 u	3 u	2 u	6 u

The total number of stickers is repeated.  Make the total number of stickers the same.  LCM of 3 and 6 is 6.

Number of stickers that Asher has more than Henry
= 3 u - 1 u
= 2 u

2 u = 18

1 u = 18 ÷ 2 = 9

	Henry	Asher	Zeph
Before	1 u	3 u	2 u
Change	+ 2 u	- 3 u	+ 1 u
After	3 u	0 u	3 u

Number of stickers that Henry has received from Asher
= 3 u - 1 u 
= 2 u
= 2 x 9
= 18

Answer(s): 18
