A stall was selling flowers. ¹₄ of the earnings are from the sale of 10 sunflowers and 10 daffodils. Of the rest of the earnings, ³₅ are from the sale of sunflowers and ²₅ are from the sale of daffodils. Each daffodil costs thrice as much as each sunflower. How many flowers were sold?

10 sunflowers and 10 daffodils	Rest of the earnings		Total earnings
1x5	3x5
	Roses	Carnations
	3x3	2x3
5	9	6	20

Fraction of the earnings left after the sale of 10 sunflowers and 10 daffodils
= 1 - ¹₄
= ³₄ 

The rest of the earnings is repeated. LCM of 3 and 5 is 15.

Cost of 1 sunflower = 1 u
Cost of 1 daffodil = 3 u

Cost of 10 sunflowers = 10 x 1 u = 10 u
Cost of 10 daffodils = 10 x 3 u = 30 u

Total cost of 10 sunflowers and 10 daffodils
= 10 u + 30 u
= 40 u

⁵₂₀ of the earnings → 40 u 
¹₂₀ of the earnings → 40 u ÷ 5 = 8 u 

⁹₂₀ of the earnings → 9 x 8 u = 72 u 

Number of sunflowers sold that contributed to the rest of the earnings
= 72 u ÷ 1 u
= 72

⁶₂₀ of the earnings → 6 x 8 u = 48 u

Number of daffodils sold that contributed to the rest of the earnings
= 48 u ÷ 3 u
= 16

Number of flowers sold
= 10 + 10 + 72 + 16
= 108

Answer(s): 108
