A stall was selling flowers. ¹₄ of the earnings are from the sale of 8 marigolds and 18 tulips. Of the rest of the earnings, ³₄ are from the sale of marigolds and ¹₄ are from the sale of tulips. Each tulip costs four times as much as each marigold. How many flowers were sold?

8 marigolds and 18 tulips	Rest of the earnings		Total earnings
1x4	3x4
	Roses	Carnations
	3x3	1x3
4	9	3	16

Fraction of the earnings left after the sale of 8 marigolds and 18 tulips
= 1 - ¹₄
= ³₄ 

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

Cost of 1 marigold = 1 u
Cost of 1 tulip = 4 u

Cost of 8 marigolds = 8 x 1 u = 8 u
Cost of 18 tulips = 18 x 4 u = 72 u

Total cost of 8 marigolds and 18 tulips
= 8 u + 72 u
= 80 u

⁴₁₆ of the earnings → 80 u 
¹₁₆ of the earnings → 80 u ÷ 4 = 20 u 

⁹₁₆ of the earnings → 9 x 20 u = 180 u 

Number of marigolds sold that contributed to the rest of the earnings
= 180 u ÷ 1 u
= 180

³₁₆ of the earnings → 3 x 20 u = 60 u

Number of tulips sold that contributed to the rest of the earnings
= 60 u ÷ 4 u
= 15

Number of flowers sold
= 8 + 18 + 180 + 15
= 221

Answer(s): 221
