In a box, there are lollipops of 3 colours, grey, green and red. There are 66 less red lollipops than green lollipops. The number of red lollipops is ²₃ more than the grey lollipops. Given that the number of red lollipops is 30% of the total number of lollipops in the box, how many less grey lollipops are there than green lollipops?

Grey lollipops	Green lollipops	Red lollipops
	1 u + 66	1 u
3x6		5x6
70%		30%
18%	52%	30%

1 + ²₃ = ³₃ + ²₃ = ⁵₃

Yellow lollipops : Purple lollipops = 3 : 5

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

5 x 6 = 30%

Total number of grey lollipops and green lollipops in percent
= 100% - 30%
= 70%

Number of green lollipops in percent
= 70% - 18%
= 52%

Number of more green lollipops than red lollipops in percent
= 52% - 18%
= 22%

22% = 66

1% = 66 ÷ 22 = 3

Number of less grey lollipops than green lollipops
= 52% - 18%
= 34%
= 34 x 3
= 102

Answer(s): 102
