A stall was selling flowers. ¹₅ of the earnings are from the sale of 6 carnations and 11 daisies. Of the rest of the earnings, ³₅ are from the sale of carnations and ²₅ are from the sale of daisies. Each daisy costs four times as much as each carnation. How many flowers were sold?

6 carnations and 11 daisies	Rest of the earnings		Total earnings
1x5	4x5
	Roses	Carnations
	3x4	2x4
5	12	8	25

Fraction of the earnings left after the sale of 6 carnations and 11 daisies
= 1 - ¹₅
= ⁴₅ 

The rest of the earnings is repeated. LCM of 4 and 5 is 20.

Cost of 1 carnation = 1 u
Cost of 1 daisy = 4 u

Cost of 6 carnations = 6 x 1 u = 6 u
Cost of 11 daisies = 11 x 4 u = 44 u

Total cost of 6 carnations and 11 daisies
= 6 u + 44 u
= 50 u

⁵₂₅ of the earnings → 50 u 
¹₂₅ of the earnings → 50 u ÷ 5 = 10 u 

¹²₂₅ of the earnings → 12 x 10 u = 120 u 

Number of carnations sold that contributed to the rest of the earnings
= 120 u ÷ 1 u
= 120

⁸₂₅ of the earnings → 8 x 10 u = 80 u

Number of daisies sold that contributed to the rest of the earnings
= 80 u ÷ 4 u
= 20

Number of flowers sold
= 6 + 11 + 120 + 20
= 157

Answer(s): 157
