Given : The door makes 4 complete rotations in 2 minutes. There is room for a maximum two people in each of the three door sectors.

To Find :  What is the maximum number of people that can enter the building through the door in 20 minutes

Solution:

room for a maximum 2  people in each of the three door sectors

=> 2x 3 = 6  people can enter in 1 rotation.

The door makes 4 complete rotations in 2 minutes

=> Door makes  40  complete rotations in 20 minutes

In 1 rotation people can enter = 6

=> in 40 rotations people can enter = 6 x 40

=>  in 40 rotations people can enter = 240

maximum number of people that can enter the building through the door in 20 minutes = 240
