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
Pink	2
Gold	4
Red	7

In each container, the number of pink balls was 60% more than the number of red balls and 30% less than the number of gold balls. Given that the total possible points if the group managed to collect all the balls were 6770 points, how many balls were not pink in colour?

Pink	Gold	Red
8x7		5x7
7x8	10x8
56 u	80 u	35 u

	Pink	Gold	Red	Total
Number	56 u	80 u	35u
Value	2	4	7
Total value	112 u	320 u	245 u	677 u

100% + 60% = 160%
160% = ¹⁶⁰₁₀₀ =⁸₅

100% - 30% = 70%
70% = ⁷⁰₁₀₀ = ⁷₁₀

Total number of points collected
= 112 u + 320 u + 245 u
= 677 u

677 u = 6770

1 u = 6770 ÷ 677 = 10

Number of balls not pink in colour
= 80 u + 35 u
= 115 u
= 115 x 10
= 1150

Answer: 1150
