In a container, there are chocolate bars of 3 colours, silver, green and brown. There are 6 more green chocolate bars than brown chocolate bars. The number of brown chocolate bars is ¹₄ more than the silver chocolate bars. Given that the number of brown chocolate bars is 35% of the total number of chocolate bars in the container, how many more green chocolate bars are there than silver chocolate bars?

Silver chocolate bars	Green chocolate bars	Brown chocolate bars
	1 u + 6	1 u
4x7		5x7
65%		35%
28%	37%	35%

1 + ¹₄ = ⁴₄ + ¹₄ = ⁵₄

Yellow chocolate bars : Purple chocolate bars = 4 : 5

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

5 x 7 = 35%

Total number of silver chocolate bars and green chocolate bars in percent
= 100% - 35%
= 65%

Number of green chocolate bars in percent
= 65% - 28%
= 37%

Number of more green chocolate bars than brown chocolate bars in percent
= 37% - 28%
= 2%

2% = 6

1% = 6 ÷ 2 = 3

Number of more green chocolate bars than silver chocolate bars
= 37% - 28%
= 9%
= 9 x 3
= 27

Answer(s): 27
