Pierre, Jack and Corwin collected stickers in the ratio of 11 : 8 : 10. After Corwin gave ³₅ to Pierre and Jack, Corwin had 306 less stickers than Pierre. The number of stickers that Jack had increased by 35%. How many stickers did Pierre and Corwin have in the end?

	Pierre	Jack	Corwin
Before	11 u	8 u	10 u
Change	+ 3.2 u	+ 2.8 u	- 6 u
After	14.2 u	10.8 u	4 u

Number of stickers that Corwin gave to Pierre and Jack
= ³₅ x 10 u
= 6 u

Number of stickers that Jack received from Corwin
= ³⁵₁₀₀ x 8 u
= 2.8 u

Number of stickers that Pierre received from Corwin
= 6 u - 2.8 u
= 3.2 u

Number of less stickers that Corwin had less than Pierre
= 14.2 u - 4 u 
= 10.2 u

10.2 u = 306

1 u = 306 ÷ 10.2 = 30

Number of stickers that Pierre and Corwin had
= 14.2 u + 4 u
= 18.2 u
= 18.2 x 30
= 546

Answer(s): 546
