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
Silver	2
Purple	4
Black	7

In each container, the number of silver beads was 60% more than the number of black beads and 30% less than the number of purple beads. Given that the total possible points if the group managed to collect all the beads were 1354 points, how many beads were not silver in colour?

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

	Silver	Purple	Black	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 = 1354

1 u = 1354 ÷ 677 = 2

Number of beads not purple in colour
= 56 u + 35 u
= 91 u
= 91 x 2
= 182

Answer: 182
