A stall was selling flowers. ¹₅ of the earnings are from the sale of 7 daffodils and 17 daisies. Of the rest of the earnings, ²₃ are from the sale of daffodils and ¹₃ are from the sale of daisies. Each daisy costs four times as much as each daffodil. How many flowers were sold?

7 daffodils and 17 daisies	Rest of the earnings		Total earnings
1x3	4x3
	Roses	Carnations
	2x4	1x4
3	8	4	15

Fraction of the earnings left after the sale of 7 daffodils and 17 daisies
= 1 - ¹₅
= ⁴₅ 

The rest of the earnings is repeated. LCM of 4 and 3 is 12.

Cost of 1 daffodil = 1 u
Cost of 1 daisy = 4 u

Cost of 7 daffodils = 7 x 1 u = 7 u
Cost of 17 daisies = 17 x 4 u = 68 u

Total cost of 7 daffodils and 17 daisies
= 7 u + 68 u
= 75 u

³₁₅ of the earnings → 75 u 
¹₁₅ of the earnings → 75 u ÷ 3 = 25 u 

⁸₁₅ of the earnings → 8 x 25 u = 200 u 

Number of daffodils sold that contributed to the rest of the earnings
= 200 u ÷ 1 u
= 200

⁴₁₅ of the earnings → 4 x 25 u = 100 u

Number of daisies sold that contributed to the rest of the earnings
= 100 u ÷ 4 u
= 25

Number of flowers sold
= 7 + 17 + 200 + 25
= 249

Answer(s): 249
