During a telematch, each group of students was supposed to collect as many coloured balls as possible. Each colour represented a certain point as tabulated:

Colours	Points
Green	4
Brown	7
Red	9

In each container, the number of green balls was 40% more than the number of red balls and 10% less than the number of brown balls. Given that the total possible points if the group managed to collect all the balls were 2294 points, how many balls were not green in colour?

Green	Brown	Red
7x9		5x9
9x7	10x7
63 u	70 u	45 u

	Green	Brown	Red	Total
Number	63 u	70 u	45u
Value	4	7	9
Total value	252 u	490 u	405 u	1147 u

100% + 40% = 140%
140% = ¹⁴⁰₁₀₀ =⁷₅

100% - 10% = 90%
90% = ⁹⁰₁₀₀ = ⁹₁₀

Total number of points collected
= 252 u + 490 u + 405 u
= 1147 u

1147 u = 2294

1 u = 2294 ÷ 1147 = 2

Number of balls not green in colour
= 70 u + 45 u
= 115 u
= 115 x 2
= 230

Answer: 230
