In a box, there are candy canes of 3 colours, yellow, brown and green. There are 360 more brown candy canes than green candy canes. The number of green candy canes is ¹₂ more than the yellow candy canes. Given that the number of green candy canes is 15% of the total number of candy canes in the box, how many more brown candy canes are there than yellow candy canes?

Yellow candy canes	Brown candy canes	Green candy canes
	1 u + 360	1 u
2x5		3x5
85%		15%
10%	75%	15%

1 + ¹₂ = ²₂ + ¹₂ = ³₂

Yellow candy canes : Purple candy canes = 2 : 3

The number of green candy canes is repeated.  Make the number of green candy canes the same.

3 x 5 = 15%

Total number of yellow candy canes and brown candy canes in percent
= 100% - 15%
= 85%

Number of brown candy canes in percent
= 85% - 10%
= 75%

Number of more brown candy canes than green candy canes in percent
= 75% - 10%
= 60%

60% = 360

1% = 360 ÷ 60 = 6

Number of more brown candy canes than yellow candy canes
= 75% - 10%
= 65%
= 65 x 6
= 390

Answer(s): 390
