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
Red	4
Purple	7
Pink	10

In each container, the number of red beads was 60% more than the number of pink beads and 70% less than the number of purple beads. Given that the total possible points if the group managed to collect all the beads were 5642 points, how many beads were not red in colour?

Red	Purple	Pink
8x3		5x3
3x8	10x8
24 u	80 u	15 u

	Red	Purple	Pink	Total
Number	24 u	80 u	15u
Value	4	7	10
Total value	96 u	560 u	150 u	806 u

100% + 60% = 160%
160% = ¹⁶⁰₁₀₀ =⁸₅

100% - 70% = 30%
30% = ³⁰₁₀₀ = ³₁₀

Total number of points collected
= 96 u + 560 u + 150 u
= 806 u

806 u = 5642

1 u = 5642 ÷ 806 = 7

Number of beads not purple in colour
= 24 u + 15 u
= 39 u
= 39 x 7
= 273

Answer: 273
