In a container, there are sweets of 3 colours, red, brown and green. There are 392 more brown sweets than green sweets. The number of green sweets is ¹₃ more than the red sweets. Given that the number of green sweets is 16% of the total number of sweets in the container, how many more brown sweets are there than red sweets?

Red sweets	Brown sweets	Green sweets
	1 u + 392	1 u
3x4		4x4
84%		16%
12%	72%	16%

1 + ¹₃ = ³₃ + ¹₃ = ⁴₃

Yellow sweets : Purple sweets = 3 : 4

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

4 x 4 = 16%

Total number of red sweets and brown sweets in percent
= 100% - 16%
= 84%

Number of brown sweets in percent
= 84% - 12%
= 72%

Number of more brown sweets than green sweets in percent
= 72% - 12%
= 56%

56% = 392

1% = 392 ÷ 56 = 7

Number of more brown sweets than red sweets
= 72% - 12%
= 60%
= 60 x 7
= 420

Answer(s): 420
