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
Yellow	2
Gold	4
Green	5

In each container, the number of yellow beads was 60% more than the number of green beads and 10% less than the number of gold beads. Given that the total possible points if the group managed to collect all the beads were 2067 points, how many beads were not yellow in colour?

Yellow	Gold	Green
8x9		5x9
9x8	10x8
72 u	80 u	45 u

	Yellow	Gold	Green	Total
Number	72 u	80 u	45u
Value	2	4	5
Total value	144 u	320 u	225 u	689 u

100% + 60% = 160%
160% = ¹⁶⁰₁₀₀ =⁸₅

100% - 10% = 90%
90% = ⁹⁰₁₀₀ = ⁹₁₀

Total number of points collected
= 144 u + 320 u + 225 u
= 689 u

689 u = 2067

1 u = 2067 ÷ 689 = 3

Number of beads not yellow in colour
= 80 u + 45 u
= 125 u
= 125 x 3
= 375

Answer: 375
