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
Blue	4
White	6
Green	8

In each container, the number of blue beads was 40% more than the number of green beads and 70% less than the number of white beads. Given that the total possible points if the group managed to collect all the beads were 3120 points, how many beads were not blue in colour?

Blue	White	Green
7x3		5x3
3x7	10x7
21 u	70 u	15 u

	Blue	White	Green	Total
Number	21 u	70 u	15u
Value	4	6	8
Total value	84 u	420 u	120 u	624 u

100% + 40% = 140%
140% = ¹⁴⁰₁₀₀ =⁷₅

100% - 70% = 30%
30% = ³⁰₁₀₀ = ³₁₀

Total number of points collected
= 84 u + 420 u + 120 u
= 624 u

624 u = 3120

1 u = 3120 ÷ 624 = 5

Number of beads not blue in colour
= 70 u + 15 u
= 85 u
= 85 x 5
= 425

Answer: 425
