A stall was selling flowers. ¹₅ of the earnings are from the sale of 12 sunflowers and 14 poppies. Of the rest of the earnings, ³₅ are from the sale of sunflowers and ²₅ are from the sale of poppies. Each poppy costs twice as much as each sunflower. How many flowers were sold?

12 sunflowers and 14 poppies	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 12 sunflowers and 14 poppies
= 1 - ¹₅
= ⁴₅ 

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

Cost of 1 sunflower = 1 u
Cost of 1 poppy = 2 u

Cost of 12 sunflowers = 12 x 1 u = 12 u
Cost of 14 poppies = 14 x 2 u = 28 u

Total cost of 12 sunflowers and 14 poppies
= 12 u + 28 u
= 40 u

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

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

Number of sunflowers sold that contributed to the rest of the earnings
= 96 u ÷ 1 u
= 96

⁸₂₅ of the earnings → 8 x 8 u = 64 u

Number of poppies sold that contributed to the rest of the earnings
= 64 u ÷ 2 u
= 32

Number of flowers sold
= 12 + 14 + 96 + 32
= 154

Answer(s): 154
