Question

If 10 persons are served with tea cups and one person drinks the cup of tea in 5 minutes then how much time will be taken by 10 persons to drink a cup of tea?

Answer 1

Since the tea is served to all 10 persons at the same time. So, all the persons will drink and finish it simultaneously.

Hence, time taken by 10 persons to drink a cup of tea = time taken by each persons to drink a cup of tea = 5 minutes.
