30 percent of the flowers in a basket are roses. 15% of them are carnations and the remaining flowers are orchids. If there are 120 flowers altogether how many orchids are there?
First, we need to calculate the number of roses and carnations in the basket:
Roses: 30% of 120 = 0.30 x 120 = 36 roses
Carnations: 15% of 120 = 0.15 x 120 = 18 carnations
Now, we can find the total number of orchids:
Total flowers = Roses + Carnations + Orchids
120 = 36 + 18 + Orchids
Orchids = 120 - 36 - 18
Orchids = 66
Therefore, there are 66 orchids in the basket.
