In a box, there are chocolate bars of 3 colours, yellow, white and red. There are 300 more white chocolate bars than red chocolate bars. The number of red chocolate bars is ¹₄ more than the yellow chocolate bars. Given that the number of red chocolate bars is 25% of the total number of chocolate bars in the box, how many more white chocolate bars are there than yellow chocolate bars?

Yellow chocolate bars	White chocolate bars	Red chocolate bars
	1 u + 300	1 u
4x5		5x5
75%		25%
20%	55%	25%

1 + ¹₄ = ⁴₄ + ¹₄ = ⁵₄

Yellow chocolate bars : Purple chocolate bars = 4 : 5

The number of red chocolate bars is repeated.  Make the number of red chocolate bars the same.

5 x 5 = 25%

Total number of yellow chocolate bars and white chocolate bars in percent
= 100% - 25%
= 75%

Number of white chocolate bars in percent
= 75% - 20%
= 55%

Number of more white chocolate bars than red chocolate bars in percent
= 55% - 20%
= 30%

30% = 300

1% = 300 ÷ 30 = 10

Number of more white chocolate bars than yellow chocolate bars
= 55% - 20%
= 35%
= 35 x 10
= 350

Answer(s): 350
