In a box, there are lollipops of 3 colours, white, red and brown. There are 360 less brown lollipops than red lollipops. The number of brown lollipops is ¹₂ more than the white lollipops. Given that the number of brown lollipops is 15% of the total number of lollipops in the box, how many less white lollipops are there than red lollipops?

White lollipops	Red lollipops	Brown lollipops
	1 u + 360	1 u
2x5		3x5
85%		15%
10%	75%	15%

1 + ¹₂ = ²₂ + ¹₂ = ³₂

Yellow lollipops : Purple lollipops = 2 : 3

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

3 x 5 = 15%

Total number of white lollipops and red lollipops in percent
= 100% - 15%
= 85%

Number of red lollipops in percent
= 85% - 10%
= 75%

Number of more red lollipops than brown lollipops in percent
= 75% - 10%
= 60%

60% = 360

1% = 360 ÷ 60 = 6

Number of less white lollipops than red lollipops
= 75% - 10%
= 65%
= 65 x 6
= 390

Answer(s): 390
