In a box, there are chocolate bars of 3 colours, grey, pink and red. There are 352 more pink chocolate bars than red chocolate bars. The number of red chocolate bars is ¹₄ more than the grey chocolate bars. Given that the number of red chocolate bars is 20% of the total number of chocolate bars in the box, how many more pink chocolate bars are there than grey chocolate bars?

Grey chocolate bars	Pink chocolate bars	Red chocolate bars
	1 u + 352	1 u
4x4		5x4
80%		20%
16%	64%	20%

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 4 = 20%

Total number of grey chocolate bars and pink chocolate bars in percent
= 100% - 20%
= 80%

Number of pink chocolate bars in percent
= 80% - 16%
= 64%

Number of more pink chocolate bars than red chocolate bars in percent
= 64% - 16%
= 44%

44% = 352

1% = 352 ÷ 44 = 8

Number of more pink chocolate bars than grey chocolate bars
= 64% - 16%
= 48%
= 48 x 8
= 384

Answer(s): 384
