Question:

If 20 persons can do a work in 15 days, then how many more persons are required to do it in 10 days ?

Options:

15

30

10

20

Correct Answer:

10

Explanation:

We have,

20 persons can do a work in 15 days

Total work = Persons × Time = 20 × 15 = 300

Now this work has to be completed in 10 days,

so the persons required = 300/10 = 30

Extra workers = 30 - 20 = 10
