Riordan, Wesley and Cyrus collected coins in the ratio of 9 : 4 : 8. After Cyrus gave ³₅ to Riordan and Wesley, Cyrus had 328 less coins than Riordan. The number of coins that Wesley had increased by 60%. How many coins did Riordan and Cyrus have in the end?

	Riordan	Wesley	Cyrus
Before	9 u	4 u	8 u
Change	+ 2.4 u	+ 2.4 u	- 4.8 u
After	11.4 u	6.4 u	3.2 u

Number of coins that Cyrus gave to Riordan and Wesley
= ³₅ x 8 u
= 4.8 u

Number of coins that Wesley received from Cyrus
= ⁶⁰₁₀₀ x 4 u
= 2.4 u

Number of coins that Riordan received from Cyrus
= 4.8 u - 2.4 u
= 2.4 u

Number of less coins that Cyrus had less than Riordan
= 11.4 u - 3.2 u 
= 8.2 u

8.2 u = 328

1 u = 328 ÷ 8.2 = 40

Number of coins that Riordan and Cyrus had
= 11.4 u + 3.2 u
= 14.6 u
= 14.6 x 40
= 584

Answer(s): 584
