In a box, there are jelly beans of 3 colours, grey, yellow and white. There are 134 more yellow jelly beans than white jelly beans. The number of white jelly beans is ¹₃ more than the grey jelly beans. Given that the number of white jelly beans is 12% of the total number of jelly beans in the box, how many more yellow jelly beans are there than grey jelly beans?

Grey jelly beans	Yellow jelly beans	White jelly beans
	1 u + 134	1 u
3x3		4x3
88%		12%
9%	79%	12%

1 + ¹₃ = ³₃ + ¹₃ = ⁴₃

Yellow jelly beans : Purple jelly beans = 3 : 4

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

4 x 3 = 12%

Total number of grey jelly beans and yellow jelly beans in percent
= 100% - 12%
= 88%

Number of yellow jelly beans in percent
= 88% - 9%
= 79%

Number of more yellow jelly beans than white jelly beans in percent
= 79% - 9%
= 67%

67% = 134

1% = 134 ÷ 67 = 2

Number of more yellow jelly beans than grey jelly beans
= 79% - 9%
= 70%
= 70 x 2
= 140

Answer(s): 140
