Brandon, John and Clint collected erasers in the ratio of 8 : 5 : 8. After Clint gave ³₄ to Brandon and John, Clint had 285 less erasers than Brandon. The number of erasers that John had increased by 50%. How many erasers did Brandon and Clint have in the end?

	Brandon	John	Clint
Before	8 u	5 u	8 u
Change	+ 3.5 u	+ 2.5 u	- 6 u
After	11.5 u	7.5 u	2 u

Number of erasers that Clint gave to Brandon and John
= ³₄ x 8 u
= 6 u

Number of erasers that John received from Clint
= ⁵⁰₁₀₀ x 5 u
= 2.5 u

Number of erasers that Brandon received from Clint
= 6 u - 2.5 u
= 3.5 u

Number of less erasers that Clint had less than Brandon
= 11.5 u - 2 u 
= 9.5 u

9.5 u = 285

1 u = 285 ÷ 9.5 = 30

Number of erasers that Brandon and Clint had
= 11.5 u + 2 u
= 13.5 u
= 13.5 x 30
= 405

Answer(s): 405
