In a container, there are chocolate bars of 3 colours, white, silver and blue. There are 170 more silver chocolate bars than blue chocolate bars. The number of blue chocolate bars is ¹₃ more than the white chocolate bars. Given that the number of blue chocolate bars is 24% of the total number of chocolate bars in the container, how many more silver chocolate bars are there than white chocolate bars?

White chocolate bars	Silver chocolate bars	Blue chocolate bars
	1 u + 170	1 u
3x6		4x6
76%		24%
18%	58%	24%

1 + ¹₃ = ³₃ + ¹₃ = ⁴₃

Yellow chocolate bars : Purple chocolate bars = 3 : 4

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

4 x 6 = 24%

Total number of white chocolate bars and silver chocolate bars in percent
= 100% - 24%
= 76%

Number of silver chocolate bars in percent
= 76% - 18%
= 58%

Number of more silver chocolate bars than blue chocolate bars in percent
= 58% - 18%
= 34%

34% = 170

1% = 170 ÷ 34 = 5

Number of more silver chocolate bars than white chocolate bars
= 58% - 18%
= 40%
= 40 x 5
= 200

Answer(s): 200
