A stall was selling flowers. ¹₅ of the earnings are from the sale of 7 poppies and 11 roses. Of the rest of the earnings, ²₅ are from the sale of poppies and ³₅ are from the sale of roses. Each rose costs thrice as much as each poppy. How many flowers were sold?

7 poppies and 11 roses	Rest of the earnings		Total earnings
1x5	4x5
	Roses	Carnations
	2x4	3x4
5	8	12	25

Fraction of the earnings left after the sale of 7 poppies and 11 roses
= 1 - ¹₅
= ⁴₅ 

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

Cost of 1 poppy = 1 u
Cost of 1 rose = 3 u

Cost of 7 poppies = 7 x 1 u = 7 u
Cost of 11 roses = 11 x 3 u = 33 u

Total cost of 7 poppies and 11 roses
= 7 u + 33 u
= 40 u

⁵₂₅ of the earnings → 40 u 
¹₂₅ of the earnings → 40 u ÷ 5 = 8 u 

⁸₂₅ of the earnings → 8 x 8 u = 64 u 

Number of poppies sold that contributed to the rest of the earnings
= 64 u ÷ 1 u
= 64

¹²₂₅ of the earnings → 12 x 8 u = 96 u

Number of roses sold that contributed to the rest of the earnings
= 96 u ÷ 3 u
= 32

Number of flowers sold
= 7 + 11 + 64 + 32
= 114

Answer(s): 114
