Question

Q1. 10 workers finish a job in 6 days. In how many days will 20 workers finish the same job?

Answer 1

Answer:

Step-by-step explanation:

When the no. of workers will increase then the no. of days will decrease.

Therefore, no. of workers is inversely proportional to the no. of days.

Let 20 workers will require X days to complete the job.

Therefore,      10/20 = 6/X

                       10 × X = 6 × 20

                              X = 6 × 20/10

                              X = 6 × 2

                              X = 12.

Therefore, 20 workers will require 12 days to finish the same job.

                       

Answer 2

Step-by-step explanation:

10 workers = 6 days

1 worker = (10×6) days

20 workers = (10×6/20) days

= 3 days
