Gabriel, Archie and Clayton collected erasers in the ratio of 8 : 7 : 9. After Clayton gave ⁴₅ to Gabriel and Archie, Clayton had 127 less erasers than Gabriel. The number of erasers that Archie had increased by 10%. How many erasers did Gabriel and Clayton have in the end?

	Gabriel	Archie	Clayton
Before	8 u	7 u	9 u
Change	+ 6.5 u	+ 0.7 u	- 7.2 u
After	14.5 u	7.7 u	1.8 u

Number of erasers that Clayton gave to Gabriel and Archie
= ⁴₅ x 9 u
= 7.2 u

Number of erasers that Archie received from Clayton
= ¹⁰₁₀₀ x 7 u
= 0.7 u

Number of erasers that Gabriel received from Clayton
= 7.2 u - 0.7 u
= 6.5 u

Number of less erasers that Clayton had less than Gabriel
= 14.5 u - 1.8 u 
= 12.7 u

12.7 u = 127

1 u = 127 ÷ 12.7 = 10

Number of erasers that Gabriel and Clayton had
= 14.5 u + 1.8 u
= 16.3 u
= 16.3 x 10
= 163

Answer(s): 163
