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
Brown	2
Yellow	3
Pink	5

In each container, the number of brown balls was 20% more than the number of pink balls and 70% less than the number of yellow balls. Given that the total possible points if the group managed to collect all the balls were 776 points, how many balls were not brown in colour?

Brown	Yellow	Pink
6x1		5x1
3x2	10x2
6 u	20 u	5 u

	Brown	Yellow	Pink	Total
Number	6 u	20 u	5u
Value	2	3	5
Total value	12 u	60 u	25 u	97 u

100% + 20% = 120%
120% = ¹²⁰₁₀₀ =⁶₅

100% - 70% = 30%
30% = ³⁰₁₀₀ = ³₁₀

Total number of points collected
= 12 u + 60 u + 25 u
= 97 u

97 u = 776

1 u = 776 ÷ 97 = 8

Number of balls not brown in colour
= 20 u + 5 u
= 25 u
= 25 x 8
= 200

Answer: 200
