During a telematch, each group of students was supposed to collect as many coloured balls as possible. Each colour represented a certain point as tabulated:

Colours	Points
Brown	4
Green	6
White	7

In each container, the number of brown balls was 60% more than the number of white balls and 30% less than the number of green balls. Given that the total possible points if the group managed to collect all the balls were 7592 points, how many balls were not brown in colour?

Brown	Green	White
8x7		5x7
7x8	10x8
56 u	80 u	35 u

	Brown	Green	White	Total
Number	56 u	80 u	35u
Value	4	6	7
Total value	224 u	480 u	245 u	949 u

100% + 60% = 160%
160% = ¹⁶⁰₁₀₀ =⁸₅

100% - 30% = 70%
70% = ⁷⁰₁₀₀ = ⁷₁₀

Total number of points collected
= 224 u + 480 u + 245 u
= 949 u

949 u = 7592

1 u = 7592 ÷ 949 = 8

Number of balls not brown in colour
= 80 u + 35 u
= 115 u
= 115 x 8
= 920

Answer: 920
