In a container, there are sweets of 3 colours, yellow, green and brown. There are 441 less brown sweets than green sweets. The number of brown sweets is ¹₅ more than the yellow sweets. Given that the number of brown sweets is 18% of the total number of sweets in the container, how many less yellow sweets are there than green sweets?

Yellow sweets	Green sweets	Brown sweets
	1 u + 441	1 u
5x3		6x3
82%		18%
15%	67%	18%

1 + ¹₅ = ⁵₅ + ¹₅ = ⁶₅

Yellow sweets : Purple sweets = 5 : 6

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

6 x 3 = 18%

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

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

Number of more green sweets than brown sweets in percent
= 67% - 15%
= 49%

49% = 441

1% = 441 ÷ 49 = 9

Number of less yellow sweets than green sweets
= 67% - 15%
= 52%
= 52 x 9
= 468

Answer(s): 468
