A stall was selling flowers. ¹₃ of the earnings are from the sale of 6 daisies and 16 sunflowers. Of the rest of the earnings, ²₅ are from the sale of daisies and ³₅ are from the sale of sunflowers. Each sunflower costs four times as much as each daisy. How many flowers were sold?

6 daisies and 16 sunflowers	Rest of the earnings		Total earnings
1x5	2x5
	Roses	Carnations
	2x2	3x2
5	4	6	15

Fraction of the earnings left after the sale of 6 daisies and 16 sunflowers
= 1 - ¹₃
= ²₃ 

The rest of the earnings is repeated. LCM of 2 and 5 is 10.

Cost of 1 daisy = 1 u
Cost of 1 sunflower = 4 u

Cost of 6 daisies = 6 x 1 u = 6 u
Cost of 16 sunflowers = 16 x 4 u = 64 u

Total cost of 6 daisies and 16 sunflowers
= 6 u + 64 u
= 70 u

⁵₁₅ of the earnings → 70 u 
¹₁₅ of the earnings → 70 u ÷ 5 = 14 u 

⁴₁₅ of the earnings → 4 x 14 u = 56 u 

Number of daisies sold that contributed to the rest of the earnings
= 56 u ÷ 1 u
= 56

⁶₁₅ of the earnings → 6 x 14 u = 84 u

Number of sunflowers sold that contributed to the rest of the earnings
= 84 u ÷ 4 u
= 21

Number of flowers sold
= 6 + 16 + 56 + 21
= 99

Answer(s): 99
