In a box, there are lollipops of 3 colours, blue, green and brown. There are 240 less brown lollipops than green lollipops. The number of brown lollipops is ¹₄ more than the blue lollipops. Given that the number of brown lollipops is 25% of the total number of lollipops in the box, how many less blue lollipops are there than green lollipops?

Blue lollipops	Green lollipops	Brown lollipops
	1 u + 240	1 u
4x5		5x5
75%		25%
20%	55%	25%

1 + ¹₄ = ⁴₄ + ¹₄ = ⁵₄

Yellow lollipops : Purple lollipops = 4 : 5

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

5 x 5 = 25%

Total number of blue lollipops and green lollipops in percent
= 100% - 25%
= 75%

Number of green lollipops in percent
= 75% - 20%
= 55%

Number of more green lollipops than brown lollipops in percent
= 55% - 20%
= 30%

30% = 240

1% = 240 ÷ 30 = 8

Number of less blue lollipops than green lollipops
= 55% - 20%
= 35%
= 35 x 8
= 280

Answer(s): 280
