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
Pink	3
Silver	6
Green	9

In each container, the number of pink beads was 60% more than the number of green beads and 90% less than the number of silver beads. Given that the total possible points if the group managed to collect all the beads were 5490 points, how many beads were not pink in colour?

Pink	Silver	Green
8x1		5x1
1x8	10x8
8 u	80 u	5 u

	Pink	Silver	Green	Total
Number	8 u	80 u	5u
Value	3	6	9
Total value	24 u	480 u	45 u	549 u

100% + 60% = 160%
160% = ¹⁶⁰₁₀₀ =⁸₅

100% - 90% = 10%
10% = ¹⁰₁₀₀ = ¹₁₀

Total number of points collected
= 24 u + 480 u + 45 u
= 549 u

549 u = 5490

1 u = 5490 ÷ 549 = 10

Number of beads not silver in colour
= 8 u + 5 u
= 13 u
= 13 x 10
= 130

Answer: 130
