Bryan, Owen and Brandon have some stickers. The ratios of their stickers are as follows:

Bryan : (Bryan + Owen + Brandon) = 3 : 7
Owen : (Bryan + Brandon) = 1 : 3

Brandon has 22 stickers more than Owen. In the end, Brandon gives away all he has to Owen and Bryan so that both Owen and Bryan end up with the same number of stickers, how many stickers has Bryan received from Brandon?

Owen	Brandon	Bryan	Total
4x4		3x4	7x4
1x7	3x7		4x7
7 u	9 u	12 u	28 u

The total number of stickers is repeated.  Make the total number of stickers the same.  LCM of 7 and 4 is 28.

Number of stickers that Brandon has more than Owen
= 9 u - 7 u
= 2 u

2 u = 22

1 u = 22 ÷ 2 = 11

	Owen	Brandon	Bryan
Before	7 u	9 u	12 u
Change	+ 7 u	- 9 u	+ 2 u
After	14 u	0 u	14 u

Number of stickers that Bryan has received from Brandon
= 14 u - 12 u 
= 2 u
= 2 x 11
= 22

Answer(s): 22
