A stall was selling flowers. ¹₅ of the earnings are from the sale of 8 roses and 11 poppies. Of the rest of the earnings, ²₅ are from the sale of roses and ³₅ are from the sale of poppies. Each poppy costs twice as much as each rose. How many flowers were sold?

8 roses and 11 poppies	Rest of the earnings		Total earnings
1x5	4x5
	Roses	Carnations
	2x4	3x4
5	8	12	25

Fraction of the earnings left after the sale of 8 roses and 11 poppies
= 1 - ¹₅
= ⁴₅ 

The rest of the earnings is repeated. LCM of 4 and 5 is 20.

Cost of 1 rose = 1 u
Cost of 1 poppy = 2 u

Cost of 8 roses = 8 x 1 u = 8 u
Cost of 11 poppies = 11 x 2 u = 22 u

Total cost of 8 roses and 11 poppies
= 8 u + 22 u
= 30 u

⁵₂₅ of the earnings → 30 u 
¹₂₅ of the earnings → 30 u ÷ 5 = 6 u 

⁸₂₅ of the earnings → 8 x 6 u = 48 u 

Number of roses sold that contributed to the rest of the earnings
= 48 u ÷ 1 u
= 48

¹²₂₅ of the earnings → 12 x 6 u = 72 u

Number of poppies sold that contributed to the rest of the earnings
= 72 u ÷ 2 u
= 36

Number of flowers sold
= 8 + 11 + 48 + 36
= 103

Answer(s): 103
