A stall was selling flowers. ¹₄ of the earnings are from the sale of 11 carnations and 18 daisies. Of the rest of the earnings, ²₅ are from the sale of carnations and ³₅ are from the sale of daisies. Each daisy costs thrice as much as each carnation. How many flowers were sold?

11 carnations and 18 daisies	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 11 carnations and 18 daisies
= 1 - ¹₄
= ³₄ 

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

Cost of 1 carnation = 1 u
Cost of 1 daisy = 3 u

Cost of 11 carnations = 11 x 1 u = 11 u
Cost of 18 daisies = 18 x 3 u = 54 u

Total cost of 11 carnations and 18 daisies
= 11 u + 54 u
= 65 u

⁵₂₀ of the earnings → 65 u 
¹₂₀ of the earnings → 65 u ÷ 5 = 13 u 

⁶₂₀ of the earnings → 6 x 13 u = 78 u 

Number of carnations sold that contributed to the rest of the earnings
= 78 u ÷ 1 u
= 78

⁹₂₀ of the earnings → 9 x 13 u = 117 u

Number of daisies sold that contributed to the rest of the earnings
= 117 u ÷ 3 u
= 39

Number of flowers sold
= 11 + 18 + 78 + 39
= 146

Answer(s): 146
