In a container, there are sweets of 3 colours, gold, brown and pink. There are 520 more brown sweets than pink sweets. The number of pink sweets is ¹₂ more than the gold sweets. Given that the number of pink sweets is 18% of the total number of sweets in the container, how many more brown sweets are there than gold sweets?

Gold sweets	Brown sweets	Pink sweets
	1 u + 520	1 u
2x6		3x6
82%		18%
12%	70%	18%

1 + ¹₂ = ²₂ + ¹₂ = ³₂

Yellow sweets : Purple sweets = 2 : 3

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

3 x 6 = 18%

Total number of gold sweets and brown sweets in percent
= 100% - 18%
= 82%

Number of brown sweets in percent
= 82% - 12%
= 70%

Number of more brown sweets than pink sweets in percent
= 70% - 12%
= 52%

52% = 520

1% = 520 ÷ 52 = 10

Number of more brown sweets than gold sweets
= 70% - 12%
= 58%
= 58 x 10
= 580

Answer(s): 580
