Jack, Reggie and Clark collected stickers in the ratio of 11 : 7 : 6. After Clark gave ³₄ to Jack and Reggie, Clark had 112 less stickers than Jack. The number of stickers that Reggie had increased by 40%. How many stickers did Jack and Clark have in the end?

	Jack	Reggie	Clark
Before	11 u	7 u	6 u
Change	+ 1.7 u	+ 2.8 u	- 4.5 u
After	12.7 u	9.8 u	1.5 u

Number of stickers that Clark gave to Jack and Reggie
= ³₄ x 6 u
= 4.5 u

Number of stickers that Reggie received from Clark
= ⁴⁰₁₀₀ x 7 u
= 2.8 u

Number of stickers that Jack received from Clark
= 4.5 u - 2.8 u
= 1.7 u

Number of less stickers that Clark had less than Jack
= 12.7 u - 1.5 u 
= 11.2 u

11.2 u = 112

1 u = 112 ÷ 11.2 = 10

Number of stickers that Jack and Clark had
= 12.7 u + 1.5 u
= 14.2 u
= 14.2 x 10
= 142

Answer(s): 142
