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

Colours	Points
Gold	2
Black	5
Pink	7

In each container, the number of gold beads was 60% more than the number of pink beads and 10% less than the number of black beads. Given that the total possible points if the group managed to collect all the beads were 4295 points, how many beads were not gold in colour?

Gold	Black	Pink
8x9		5x9
9x8	10x8
72 u	80 u	45 u

	Gold	Black	Pink	Total
Number	72 u	80 u	45u
Value	2	5	7
Total value	144 u	400 u	315 u	859 u

100% + 60% = 160%
160% = ¹⁶⁰₁₀₀ =⁸₅

100% - 10% = 90%
90% = ⁹⁰₁₀₀ = ⁹₁₀

Total number of points collected
= 144 u + 400 u + 315 u
= 859 u

859 u = 4295

1 u = 4295 ÷ 859 = 5

Number of beads not black in colour
= 72 u + 45 u
= 117 u
= 117 x 5
= 585

Answer: 585
