In a box, there are jelly beans of 3 colours, brown, silver and pink. There are 760 less pink jelly beans than silver jelly beans. The number of pink jelly beans is ¹₂ more than the brown jelly beans. Given that the number of pink jelly beans is 9% of the total number of jelly beans in the box, how many less brown jelly beans are there than silver jelly beans?

Brown jelly beans	Silver jelly beans	Pink jelly beans
	1 u + 760	1 u
2x3		3x3
91%		9%
6%	85%	9%

1 + ¹₂ = ²₂ + ¹₂ = ³₂

Yellow jelly beans : Purple jelly beans = 2 : 3

The number of pink jelly beans is repeated.  Make the number of pink jelly beans the same.

3 x 3 = 9%

Total number of brown jelly beans and silver jelly beans in percent
= 100% - 9%
= 91%

Number of silver jelly beans in percent
= 91% - 6%
= 85%

Number of more silver jelly beans than pink jelly beans in percent
= 85% - 6%
= 76%

76% = 760

1% = 760 ÷ 76 = 10

Number of less brown jelly beans than silver jelly beans
= 85% - 6%
= 79%
= 79 x 10
= 790

Answer(s): 790
