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

Colours	Points
Purple	4
Brown	6
Silver	9

In each container, the number of purple balls was 60% more than the number of silver balls and 30% less than the number of brown balls. Given that the total possible points if the group managed to collect all the balls were 10190 points, how many balls were not purple in colour?

Purple	Brown	Silver
8x7		5x7
7x8	10x8
56 u	80 u	35 u

	Purple	Brown	Silver	Total
Number	56 u	80 u	35u
Value	4	6	9
Total value	224 u	480 u	315 u	1019 u

100% + 60% = 160%
160% = ¹⁶⁰₁₀₀ =⁸₅

100% - 30% = 70%
70% = ⁷⁰₁₀₀ = ⁷₁₀

Total number of points collected
= 224 u + 480 u + 315 u
= 1019 u

1019 u = 10190

1 u = 10190 ÷ 1019 = 10

Number of balls not brown in colour
= 56 u + 35 u
= 91 u
= 91 x 10
= 910

Answer: 910
