In a container, there are candy canes of 3 colours, silver, yellow and white. There are 308 more yellow candy canes than white candy canes. The number of white candy canes is ¹₂ more than the silver candy canes. Given that the number of white candy canes is 21% of the total number of candy canes in the container, how many more yellow candy canes are there than silver candy canes?

Silver candy canes	Yellow candy canes	White candy canes
	1 u + 308	1 u
2x7		3x7
79%		21%
14%	65%	21%

1 + ¹₂ = ²₂ + ¹₂ = ³₂

Yellow candy canes : Purple candy canes = 2 : 3

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

3 x 7 = 21%

Total number of silver candy canes and yellow candy canes in percent
= 100% - 21%
= 79%

Number of yellow candy canes in percent
= 79% - 14%
= 65%

Number of more yellow candy canes than white candy canes in percent
= 65% - 14%
= 44%

44% = 308

1% = 308 ÷ 44 = 7

Number of more yellow candy canes than silver candy canes
= 65% - 14%
= 51%
= 51 x 7
= 357

Answer(s): 357
