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

Colours	Points
Pink	3
Yellow	4
Blue	5

In each container, the number of pink marbles was 20% more than the number of blue marbles and 50% less than the number of yellow marbles. Given that the total possible points if the group managed to collect all the marbles were 182 points, how many marbles were not pink in colour?

Pink	Yellow	Blue
6x1		5x1
1x6	2x6
6 u	12 u	5 u

	Pink	Yellow	Blue	Total
Number	6 u	12 u	5u
Value	3	4	5
Total value	18 u	48 u	25 u	91 u

100% + 20% = 120%
120% = ¹²⁰₁₀₀ =⁶₅

100% - 50% = 50%
50% = ⁵⁰₁₀₀ = ¹₂

Total number of points collected
= 18 u + 48 u + 25 u
= 91 u

91 u = 182

1 u = 182 ÷ 91 = 2

Number of marbles not yellow in colour
= 6 u + 5 u
= 11 u
= 11 x 2
= 22

Answer: 22
