A stall was selling flowers. ¹₅ of the earnings are from the sale of 10 daffodils and 20 peonies. Of the rest of the earnings, ²₅ are from the sale of daffodils and ³₅ are from the sale of peonies. Each peony costs twice as much as each daffodil. How many flowers were sold?

10 daffodils and 20 peonies	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 10 daffodils and 20 peonies
= 1 - ¹₅
= ⁴₅ 

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

Cost of 1 daffodil = 1 u
Cost of 1 peony = 2 u

Cost of 10 daffodils = 10 x 1 u = 10 u
Cost of 20 peonies = 20 x 2 u = 40 u

Total cost of 10 daffodils and 20 peonies
= 10 u + 40 u
= 50 u

⁵₂₅ of the earnings → 50 u 
¹₂₅ of the earnings → 50 u ÷ 5 = 10 u 

⁸₂₅ of the earnings → 8 x 10 u = 80 u 

Number of daffodils sold that contributed to the rest of the earnings
= 80 u ÷ 1 u
= 80

¹²₂₅ of the earnings → 12 x 10 u = 120 u

Number of peonies sold that contributed to the rest of the earnings
= 120 u ÷ 2 u
= 60

Number of flowers sold
= 10 + 20 + 80 + 60
= 170

Answer(s): 170
