Fraction of the earnings left after the sale of 10 poppies and 10 tulips
= 1 -
14 =
34 The rest of the earnings is repeated. LCM of 3 and 5 is 15.
Cost of 1 poppy = 1 u
Cost of 1 tulip = 2 u
Cost of 10 poppies = 10 x 1 u = 10 u
Cost of 10 tulips = 10 x 2 u = 20 u
Total cost of 10 poppies and 10 tulips
= 10 u + 20 u
= 30 u
520 of the earnings → 30 u
120 of the earnings → 30 u ÷ 5 = 6 u
920 of the earnings → 9 x 6 u = 54 u
Number of poppies sold that contributed to the rest of the earnings
= 54 u ÷ 1 u
= 54
620 of the earnings → 6 x 6 u = 36 u
Number of tulips sold that contributed to the rest of the earnings
= 36 u ÷ 2 u
= 18
Number of flowers sold
= 10 + 10 + 54 + 18
= 92
Answer(s): 92
