Fraction of the earnings left after the sale of 10 daffodils and 10 daisies
= 1 -
13 =
23 The rest of the earnings is repeated. LCM of 2 and 5 is 10.
Cost of 1 daffodil = 1 u
Cost of 1 daisy = 3 u
Cost of 10 daffodils = 10 x 1 u = 10 u
Cost of 10 daisies = 10 x 3 u = 30 u
Total cost of 10 daffodils and 10 daisies
= 10 u + 30 u
= 40 u
515 of the earnings → 40 u
115 of the earnings → 40 u ÷ 5 = 8 u
415 of the earnings → 4 x 8 u = 32 u
Number of daffodils sold that contributed to the rest of the earnings
= 32 u ÷ 1 u
= 32
615 of the earnings → 6 x 8 u = 48 u
Number of daisies sold that contributed to the rest of the earnings
= 48 u ÷ 3 u
= 16
Number of flowers sold
= 10 + 10 + 32 + 16
= 68
