Fraction of the earnings left after the sale of 10 lilies and 10 sunflowers
= 1 -
13 =
23 The rest of the earnings is repeated. LCM of 2 and 5 is 10.
Cost of 1 lily = 1 u
Cost of 1 sunflower = 4 u
Cost of 10 lilies = 10 x 1 u = 10 u
Cost of 10 sunflowers = 10 x 4 u = 40 u
Total cost of 10 lilies and 10 sunflowers
= 10 u + 40 u
= 50 u
515 of the earnings → 50 u
115 of the earnings → 50 u ÷ 5 = 10 u
615 of the earnings → 6 x 10 u = 60 u
Number of lilies sold that contributed to the rest of the earnings
= 60 u ÷ 1 u
= 60
415 of the earnings → 4 x 10 u = 40 u
Number of sunflowers sold that contributed to the rest of the earnings
= 40 u ÷ 4 u
= 10
Number of flowers sold
= 10 + 10 + 60 + 10
= 90
Answer(s): 90
