Fraction of the earnings left after the sale of 11 carnations and 15 orchids
= 1 -
14 =
34 The rest of the earnings is repeated. LCM of 3 and 4 is 12.
Cost of 1 carnation = 1 u
Cost of 1 orchid = 3 u
Cost of 11 carnations = 11 x 1 u = 11 u
Cost of 15 orchids = 15 x 3 u = 45 u
Total cost of 11 carnations and 15 orchids
= 11 u + 45 u
= 56 u
416 of the earnings → 56 u
116 of the earnings → 56 u ÷ 4 = 14 u
916 of the earnings → 9 x 14 u = 126 u
Number of carnations sold that contributed to the rest of the earnings
= 126 u ÷ 1 u
= 126
316 of the earnings → 3 x 14 u = 42 u
Number of orchids sold that contributed to the rest of the earnings
= 42 u ÷ 3 u
= 14
Number of flowers sold
= 11 + 15 + 126 + 14
= 166
Answer(s): 166
