In a box, there are jelly beans of 3 colours, yellow, silver and grey. There are 68 less grey jelly beans than silver jelly beans. The number of grey jelly beans is ¹₃ more than the yellow jelly beans. Given that the number of grey jelly beans is 24% of the total number of jelly beans in the box, how many less yellow jelly beans are there than silver jelly beans?

Yellow jelly beans	Silver jelly beans	Grey jelly beans
	1 u + 68	1 u
3x6		4x6
76%		24%
18%	58%	24%

1 + ¹₃ = ³₃ + ¹₃ = ⁴₃

Yellow jelly beans : Purple jelly beans = 3 : 4

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

4 x 6 = 24%

Total number of yellow jelly beans and silver jelly beans in percent
= 100% - 24%
= 76%

Number of silver jelly beans in percent
= 76% - 18%
= 58%

Number of more silver jelly beans than grey jelly beans in percent
= 58% - 18%
= 34%

34% = 68

1% = 68 ÷ 34 = 2

Number of less yellow jelly beans than silver jelly beans
= 58% - 18%
= 40%
= 40 x 2
= 80

Answer(s): 80
