Asked by Sadaf
                It takes for three gardeners 90 minutes to weed a garden. If the job is to be done in only 15 minutes, how many more gardeners need to be put on the jobs?

    each gardener takes 3*90 = 270 minutes to do the job alone.
So, since 15 = 270/18
It will take a total of 18 gardeners.
