In a container, there are lollipops of 3 colours, white, brown and pink. There are 680 less pink lollipops than brown lollipops. The number of pink lollipops is ¹₂ more than the white lollipops. Given that the number of pink lollipops is 12% of the total number of lollipops in the container, how many less white lollipops are there than brown lollipops?

White lollipops	Brown lollipops	Pink lollipops
	1 u + 680	1 u
2x4		3x4
88%		12%
8%	80%	12%

1 + ¹₂ = ²₂ + ¹₂ = ³₂

Yellow lollipops : Purple lollipops = 2 : 3

The number of pink lollipops is repeated.  Make the number of pink lollipops the same.

3 x 4 = 12%

Total number of white lollipops and brown lollipops in percent
= 100% - 12%
= 88%

Number of brown lollipops in percent
= 88% - 8%
= 80%

Number of more brown lollipops than pink lollipops in percent
= 80% - 8%
= 68%

68% = 680

1% = 680 ÷ 68 = 10

Number of less white lollipops than brown lollipops
= 80% - 8%
= 72%
= 72 x 10
= 720

Answer(s): 720
