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

Pink sweets	Red sweets	Green 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 green sweets is repeated.  Make the number of green sweets the same.

3 x 6 = 18%

Total number of pink sweets and red sweets in percent
= 100% - 18%
= 82%

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

Number of more red sweets than green sweets in percent
= 70% - 12%
= 52%

52% = 520

1% = 520 ÷ 52 = 10

Number of less pink sweets than red sweets
= 70% - 12%
= 58%
= 58 x 10
= 580

Answer(s): 580
