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?

Answer 1

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.
