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
Silver	4
Pink	6
Yellow	9

In each container, the number of silver beads was 80% more than the number of yellow beads and 70% less than the number of pink beads. Given that the total possible points if the group managed to collect all the beads were 2349 points, how many beads were not silver in colour?

Silver	Pink	Yellow
9x1		5x1
3x3	10x3
9 u	30 u	5 u

	Silver	Pink	Yellow	Total
Number	9 u	30 u	5u
Value	4	6	9
Total value	36 u	180 u	45 u	261 u

100% + 80% = 180%
180% = ¹⁸⁰₁₀₀ =⁹₅

100% - 70% = 30%
30% = ³⁰₁₀₀ = ³₁₀

Total number of points collected
= 36 u + 180 u + 45 u
= 261 u

261 u = 2349

1 u = 2349 ÷ 261 = 9

Number of beads not pink in colour
= 9 u + 5 u
= 14 u
= 14 x 9
= 126

Answer: 126
