Vincent, Henry and Chung collected marbles in the ratio of 11 : 6 : 7. After Chung gave ⁴₅ to Vincent and Henry, Chung had 107 less marbles than Vincent. The number of marbles that Henry had increased by 75%. How many marbles did Vincent and Chung have in the end?

	Vincent	Henry	Chung
Before	11 u	6 u	7 u
Change	+ 1.1 u	+ 4.5 u	- 5.6 u
After	12.1 u	10.5 u	1.4 u

Number of marbles that Chung gave to Vincent and Henry
= ⁴₅ x 7 u
= 5.6 u

Number of marbles that Henry received from Chung
= ⁷⁵₁₀₀ x 6 u
= 4.5 u

Number of marbles that Vincent received from Chung
= 5.6 u - 4.5 u
= 1.1 u

Number of less marbles that Chung had less than Vincent
= 12.1 u - 1.4 u 
= 10.7 u

10.7 u = 107

1 u = 107 ÷ 10.7 = 10

Number of marbles that Vincent and Chung had
= 12.1 u + 1.4 u
= 13.5 u
= 13.5 x 10
= 135

Answer(s): 135
