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

Colours	Points
Pink	3
Gold	4
Black	6

In each container, the number of pink beads was 60% more than the number of black beads and 30% less than the number of gold beads. Given that the total possible points if the group managed to collect all the beads were 4188 points, how many beads were not pink in colour?

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

	Pink	Gold	Black	Total
Number	56 u	80 u	35u
Value	3	4	6
Total value	168 u	320 u	210 u	698 u

100% + 60% = 160%
160% = ¹⁶⁰₁₀₀ =⁸₅

100% - 30% = 70%
70% = ⁷⁰₁₀₀ = ⁷₁₀

Total number of points collected
= 168 u + 320 u + 210 u
= 698 u

698 u = 4188

1 u = 4188 ÷ 698 = 6

Number of beads not pink in colour
= 80 u + 35 u
= 115 u
= 115 x 6
= 690

Answer: 690
