Flynn, Mark and Clayton collected erasers in the ratio of 11 : 4 : 10. After Clayton gave ³₁₀ to Flynn and Mark, Clayton had 92 less erasers than Flynn. The number of erasers that Mark had increased by 60%. How many erasers did Flynn and Clayton have in the end?

	Flynn	Mark	Clayton
Before	11 u	4 u	10 u
Change	+ 0.6 u	+ 2.4 u	- 3 u
After	11.6 u	6.4 u	7 u

Number of erasers that Clayton gave to Flynn and Mark
= ³₁₀ x 10 u
= 3 u

Number of erasers that Mark received from Clayton
= ⁶⁰₁₀₀ x 4 u
= 2.4 u

Number of erasers that Flynn received from Clayton
= 3 u - 2.4 u
= 0.6 u

Number of less erasers that Clayton had less than Flynn
= 11.6 u - 7 u 
= 4.6 u

4.6 u = 92

1 u = 92 ÷ 4.6 = 20

Number of erasers that Flynn and Clayton had
= 11.6 u + 7 u
= 18.6 u
= 18.6 x 20
= 372

Answer(s): 372
