In a box, there are candy canes of 3 colours, gold, black and white. There are 135 more black candy canes than white candy canes. The number of white candy canes is ¹₅ more than the gold candy canes. Given that the number of white candy canes is 30% of the total number of candy canes in the box, how many more black candy canes are there than gold candy canes?

Gold candy canes	Black candy canes	White candy canes
	1 u + 135	1 u
5x5		6x5
70%		30%
25%	45%	30%

1 + ¹₅ = ⁵₅ + ¹₅ = ⁶₅

Yellow candy canes : Purple candy canes = 5 : 6

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

6 x 5 = 30%

Total number of gold candy canes and black candy canes in percent
= 100% - 30%
= 70%

Number of black candy canes in percent
= 70% - 25%
= 45%

Number of more black candy canes than white candy canes in percent
= 45% - 25%
= 15%

15% = 135

1% = 135 ÷ 15 = 9

Number of more black candy canes than gold candy canes
= 45% - 25%
= 20%
= 20 x 9
= 180

Answer(s): 180
