In a box, there are sweets of 3 colours, green, pink and red. There are 245 more pink sweets than red sweets. The number of red sweets is ¹₅ more than the green sweets. Given that the number of red sweets is 18% of the total number of sweets in the box, how many more pink sweets are there than green sweets?

Green sweets	Pink sweets	Red sweets
	1 u + 245	1 u
5x3		6x3
82%		18%
15%	67%	18%

1 + ¹₅ = ⁵₅ + ¹₅ = ⁶₅

Yellow sweets : Purple sweets = 5 : 6

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

6 x 3 = 18%

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

Number of pink sweets in percent
= 82% - 15%
= 67%

Number of more pink sweets than red sweets in percent
= 67% - 15%
= 49%

49% = 245

1% = 245 ÷ 49 = 5

Number of more pink sweets than green sweets
= 67% - 15%
= 52%
= 52 x 5
= 260

Answer(s): 260
