Jenson, Albert and Will have some stickers. The ratios of their stickers are as follows:

Jenson : (Jenson + Albert + Will) = 3 : 7
Albert : (Jenson + Will) = 1 : 3

Will has 16 stickers more than Albert. In the end, Will gives away all he has to Albert and Jenson so that both Albert and Jenson end up with the same number of stickers, how many stickers has Albert received from Will?

Albert	Will	Jenson	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 Will has more than Albert
= 9 u - 7 u
= 2 u

2 u = 16

1 u = 16 ÷ 2 = 8

	Albert	Will	Jenson
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 Albert has received from Will
= 14 u - 7 u 
= 7 u
= 7 x 8
= 56

Answer(s): 56
