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
Purple	4
Green	6
White	7

In each container, the number of purple beads was 20% more than the number of white beads and 30% less than the number of green beads. Given that the total possible points if the group managed to collect all the beads were 1546 points, how many beads were not purple in colour?

Purple	Green	White
6x7		5x7
7x6	10x6
42 u	60 u	35 u

	Purple	Green	White	Total
Number	42 u	60 u	35u
Value	4	6	7
Total value	168 u	360 u	245 u	773 u

100% + 20% = 120%
120% = ¹²⁰₁₀₀ =⁶₅

100% - 30% = 70%
70% = ⁷⁰₁₀₀ = ⁷₁₀

Total number of points collected
= 168 u + 360 u + 245 u
= 773 u

773 u = 1546

1 u = 1546 ÷ 773 = 2

Number of beads not green in colour
= 42 u + 35 u
= 77 u
= 77 x 2
= 154

Answer: 154
