There were 420 students participating in the Swachh Bharat campaign. They cleaned4275 part of the town, Sevagram. What part of Sevagram did each student clean if thework was equally shared by all?

Answer»

Now,

They were able to clean 42/75 part of the town

And its all given that they shared the work among then equally

So,

We use what we used to call in our mid school as the unitary method

420 students = 42/75 part

So,

1 student = (42/75) / 420

1 student = 1/750

So,

1 student cleaned 1/750 part of the town
