Gabriel, Oscar and Bryan have some stickers. The ratios of their stickers are as follows:

Gabriel : (Gabriel + Oscar + Bryan) = 1 : 4
Oscar : (Gabriel + Bryan) = 1 : 4

Bryan has 49 stickers more than Oscar. In the end, Bryan gives away all he has to Oscar and Gabriel so that both Oscar and Gabriel end up with the same number of stickers, how many stickers has Gabriel received from Bryan?

Oscar	Bryan	Gabriel	Total
3x5		1x5	4x5
1x4	4x4		5x4
4 u	11 u	5 u	20 u

The total number of stickers is repeated.  Make the total number of stickers the same.  LCM of 4 and 5 is 20.

Number of stickers that Bryan has more than Oscar
= 11 u - 4 u
= 7 u

7 u = 49

1 u = 49 ÷ 7 = 7

	Oscar	Bryan	Gabriel
Before	4 u	11 u	5 u
Change	+ 6 u	- 11 u	+ 5 u
After	10 u	0 u	10 u

Number of stickers that Gabriel has received from Bryan
= 10 u - 5 u 
= 5 u
= 5 x 7
= 35

Answer(s): 35
