In a container, there are sweets of 3 colours, white, black and pink. There are 580 more black sweets than pink sweets. The number of pink sweets is ¹₄ more than the white sweets. Given that the number of pink sweets is 15% of the total number of sweets in the container, how many more black sweets are there than white sweets?

White sweets	Black sweets	Pink sweets
	1 u + 580	1 u
4x3		5x3
85%		15%
12%	73%	15%

1 + ¹₄ = ⁴₄ + ¹₄ = ⁵₄

Yellow sweets : Purple sweets = 4 : 5

The number of pink sweets is repeated.  Make the number of pink sweets the same.

5 x 3 = 15%

Total number of white sweets and black sweets in percent
= 100% - 15%
= 85%

Number of black sweets in percent
= 85% - 12%
= 73%

Number of more black sweets than pink sweets in percent
= 73% - 12%
= 58%

58% = 580

1% = 580 ÷ 58 = 10

Number of more black sweets than white sweets
= 73% - 12%
= 61%
= 61 x 10
= 610

Answer(s): 610
