In a container, there are lollipops of 3 colours, white, red and silver. There are 69 less silver lollipops than red lollipops. The number of silver lollipops is ¹₃ more than the white lollipops. Given that the number of silver lollipops is 28% of the total number of lollipops in the container, how many less white lollipops are there than red lollipops?

White lollipops	Red lollipops	Silver lollipops
	1 u + 69	1 u
3x7		4x7
72%		28%
21%	51%	28%

1 + ¹₃ = ³₃ + ¹₃ = ⁴₃

Yellow lollipops : Purple lollipops = 3 : 4

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

4 x 7 = 28%

Total number of white lollipops and red lollipops in percent
= 100% - 28%
= 72%

Number of red lollipops in percent
= 72% - 21%
= 51%

Number of more red lollipops than silver lollipops in percent
= 51% - 21%
= 23%

23% = 69

1% = 69 ÷ 23 = 3

Number of less white lollipops than red lollipops
= 51% - 21%
= 30%
= 30 x 3
= 90

Answer(s): 90
