The correct option is D 10
Number of flowers:
Roses = 60
Daisies = 50
Orchids = 30
Total number of flowers = 60 +50 + 30 = 140
Greatest number of bouquets = Highest common factor (HCF) of 60, 50, and 30
Factors of 60 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Factors of 50 = 1, 2, 5, 10, 25, 50
Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30
HCF of 30, 50, and 60 = 10
Greatest number of bouquets = 10
So, if there are a total of 140 flowers in 10 bouquets,
Number of flowers in each bouquet = 14
We can arrange this in the following manner:
Liza uses 6 roses, 5 daisies, and 3 orchids in each bouquet.
