A stall was selling flowers. ¹₅ of the earnings are from the sale of 12 marigolds and 14 daffodils. Of the rest of the earnings, ²₃ are from the sale of marigolds and ¹₃ are from the sale of daffodils. Each daffodil costs thrice as much as each marigold. How many flowers were sold?

12 marigolds and 14 daffodils	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 12 marigolds and 14 daffodils
= 1 - ¹₅
= ⁴₅ 

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

Cost of 1 marigold = 1 u
Cost of 1 daffodil = 3 u

Cost of 12 marigolds = 12 x 1 u = 12 u
Cost of 14 daffodils = 14 x 3 u = 42 u

Total cost of 12 marigolds and 14 daffodils
= 12 u + 42 u
= 54 u

³₁₅ of the earnings → 54 u 
¹₁₅ of the earnings → 54 u ÷ 3 = 18 u 

⁸₁₅ of the earnings → 8 x 18 u = 144 u 

Number of marigolds sold that contributed to the rest of the earnings
= 144 u ÷ 1 u
= 144

⁴₁₅ of the earnings → 4 x 18 u = 72 u

Number of daffodils sold that contributed to the rest of the earnings
= 72 u ÷ 3 u
= 24

Number of flowers sold
= 12 + 14 + 144 + 24
= 194

Answer(s): 194
