In a box, there are jelly beans of 3 colours, silver, white and black. There are 150 more white jelly beans than black jelly beans. The number of black jelly beans is ¹₄ more than the silver jelly beans. Given that the number of black jelly beans is 25% of the total number of jelly beans in the box, how many more white jelly beans are there than silver jelly beans?

Silver jelly beans	White jelly beans	Black jelly beans
	1 u + 150	1 u
4x5		5x5
75%		25%
20%	55%	25%

1 + ¹₄ = ⁴₄ + ¹₄ = ⁵₄

Yellow jelly beans : Purple jelly beans = 4 : 5

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

5 x 5 = 25%

Total number of silver jelly beans and white jelly beans in percent
= 100% - 25%
= 75%

Number of white jelly beans in percent
= 75% - 20%
= 55%

Number of more white jelly beans than black jelly beans in percent
= 55% - 20%
= 30%

30% = 150

1% = 150 ÷ 30 = 5

Number of more white jelly beans than silver jelly beans
= 55% - 20%
= 35%
= 35 x 5
= 175

Answer(s): 175
