In a container, there are jelly beans of 3 colours, white, yellow and silver. There are 180 less silver jelly beans than yellow jelly beans. The number of silver jelly beans is ¹₂ more than the white jelly beans. Given that the number of silver jelly beans is 15% of the total number of jelly beans in the container, how many less white jelly beans are there than yellow jelly beans?

White jelly beans	Yellow jelly beans	Silver jelly beans
	1 u + 180	1 u
2x5		3x5
85%		15%
10%	75%	15%

1 + ¹₂ = ²₂ + ¹₂ = ³₂

Yellow jelly beans : Purple jelly beans = 2 : 3

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

3 x 5 = 15%

Total number of white jelly beans and yellow jelly beans in percent
= 100% - 15%
= 85%

Number of yellow jelly beans in percent
= 85% - 10%
= 75%

Number of more yellow jelly beans than silver jelly beans in percent
= 75% - 10%
= 60%

60% = 180

1% = 180 ÷ 60 = 3

Number of less white jelly beans than yellow jelly beans
= 75% - 10%
= 65%
= 65 x 3
= 195

Answer(s): 195
