In a box, there are lollipops of 3 colours, silver, blue and grey. There are 105 more blue lollipops than grey lollipops. The number of grey lollipops is ²₃ more than the silver lollipops. Given that the number of grey lollipops is 25% of the total number of lollipops in the box, how many more blue lollipops are there than silver lollipops?

Silver lollipops	Blue lollipops	Grey lollipops
	1 u + 105	1 u
3x5		5x5
75%		25%
15%	60%	25%

1 + ²₃ = ³₃ + ²₃ = ⁵₃

Yellow lollipops : Purple lollipops = 3 : 5

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

5 x 5 = 25%

Total number of silver lollipops and blue lollipops in percent
= 100% - 25%
= 75%

Number of blue lollipops in percent
= 75% - 15%
= 60%

Number of more blue lollipops than grey lollipops in percent
= 60% - 15%
= 35%

35% = 105

1% = 105 ÷ 35 = 3

Number of more blue lollipops than silver lollipops
= 60% - 15%
= 45%
= 45 x 3
= 135

Answer(s): 135
