A stall was selling flowers. ¹₆ of the earnings are from the sale of 12 poppies and 11 marigolds. Of the rest of the earnings, ²₃ are from the sale of poppies and ¹₃ are from the sale of marigolds. Each marigold costs thrice as much as each poppy. How many flowers were sold?

12 poppies and 11 marigolds	Rest of the earnings		Total earnings
1x3	5x3
	Roses	Carnations
	2x5	1x5
3	10	5	18

Fraction of the earnings left after the sale of 12 poppies and 11 marigolds
= 1 - ¹₆
= ⁵₆ 

The rest of the earnings is repeated. LCM of 5 and 3 is 15.

Cost of 1 poppy = 1 u
Cost of 1 marigold = 3 u

Cost of 12 poppies = 12 x 1 u = 12 u
Cost of 11 marigolds = 11 x 3 u = 33 u

Total cost of 12 poppies and 11 marigolds
= 12 u + 33 u
= 45 u

³₁₈ of the earnings → 45 u 
¹₁₈ of the earnings → 45 u ÷ 3 = 15 u 

¹⁰₁₈ of the earnings → 10 x 15 u = 150 u 

Number of poppies sold that contributed to the rest of the earnings
= 150 u ÷ 1 u
= 150

⁵₁₈ of the earnings → 5 x 15 u = 75 u

Number of marigolds sold that contributed to the rest of the earnings
= 75 u ÷ 3 u
= 25

Number of flowers sold
= 12 + 11 + 150 + 25
= 198

Answer(s): 198
