Zeph, Julian and Clifford collected marbles in the ratio of 7 : 8 : 6. After Clifford gave ³₅ to Zeph and Julian, Clifford had 150 less marbles than Zeph. The number of marbles that Julian had increased by 40%. How many marbles did Zeph and Clifford have in the end?

	Zeph	Julian	Clifford
Before	7 u	8 u	6 u
Change	+ 0.4 u	+ 3.2 u	- 3.6 u
After	7.4 u	11.2 u	2.4 u

Number of marbles that Clifford gave to Zeph and Julian
= ³₅ x 6 u
= 3.6 u

Number of marbles that Julian received from Clifford
= ⁴⁰₁₀₀ x 8 u
= 3.2 u

Number of marbles that Zeph received from Clifford
= 3.6 u - 3.2 u
= 0.4 u

Number of less marbles that Clifford had less than Zeph
= 7.4 u - 2.4 u 
= 5 u

5 u = 150

1 u = 150 ÷ 5 = 30

Number of marbles that Zeph and Clifford had
= 7.4 u + 2.4 u
= 9.8 u
= 9.8 x 30
= 294

Answer(s): 294
