In a box, there are lollipops of 3 colours, purple, brown and pink. There are 603 more brown lollipops than pink lollipops. The number of pink lollipops is ¹₃ more than the purple lollipops. Given that the number of pink lollipops is 12% of the total number of lollipops in the box, how many more brown lollipops are there than purple lollipops?

Purple lollipops	Brown lollipops	Pink lollipops
	1 u + 603	1 u
3x3		4x3
88%		12%
9%	79%	12%

1 + ¹₃ = ³₃ + ¹₃ = ⁴₃

Yellow lollipops : Purple lollipops = 3 : 4

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

4 x 3 = 12%

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

Number of brown lollipops in percent
= 88% - 9%
= 79%

Number of more brown lollipops than pink lollipops in percent
= 79% - 9%
= 67%

67% = 603

1% = 603 ÷ 67 = 9

Number of more brown lollipops than purple lollipops
= 79% - 9%
= 70%
= 70 x 9
= 630

Answer(s): 630
