A stall was selling flowers. ¹₄ of the earnings are from the sale of 10 tulips and 15 poppies. Of the rest of the earnings, ²₅ are from the sale of tulips and ³₅ are from the sale of poppies. Each poppy costs twice as much as each tulip. How many flowers were sold?

10 tulips and 15 poppies	Rest of the earnings		Total earnings
1x5	3x5
	Roses	Carnations
	2x3	3x3
5	6	9	20

Fraction of the earnings left after the sale of 10 tulips and 15 poppies
= 1 - ¹₄
= ³₄ 

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

Cost of 1 tulip = 1 u
Cost of 1 poppy = 2 u

Cost of 10 tulips = 10 x 1 u = 10 u
Cost of 15 poppies = 15 x 2 u = 30 u

Total cost of 10 tulips and 15 poppies
= 10 u + 30 u
= 40 u

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

⁶₂₀ of the earnings → 6 x 8 u = 48 u 

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

⁹₂₀ of the earnings → 9 x 8 u = 72 u

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

Number of flowers sold
= 10 + 15 + 48 + 36
= 109

Answer(s): 109
