Justin, Ryan and Owen have some stickers. The ratios of their stickers are as follows:

Justin : (Justin + Ryan + Owen) = 2 : 5
Ryan : (Justin + Owen) = 1 : 5

Owen has 88 stickers more than Ryan. In the end, Owen gives away all he has to Ryan and Justin so that both Ryan and Justin end up with the same number of stickers, how many stickers has Ryan received from Owen?

Ryan	Owen	Justin	Total
3x6		2x6	5x6
1x5	5x5		6x5
5 u	13 u	12 u	30 u

The total number of stickers is repeated.  Make the total number of stickers the same.  LCM of 5 and 6 is 30.

Number of stickers that Owen has more than Ryan
= 13 u - 5 u
= 8 u

8 u = 88

1 u = 88 ÷ 8 = 11

	Ryan	Owen	Justin
Before	5 u	13 u	12 u
Change	+ 10 u	- 13 u	+ 3 u
After	15 u	0 u	15 u

Number of stickers that Ryan has received from Owen
= 15 u - 5 u 
= 10 u
= 10 x 11
= 110

Answer(s): 110
