Question

- 20 men can finish a piece of work in 30 days. After
how many days should 5 men leave the work so that
it is finished in 35 days?​

Answer 1

Answer:

15 days

Step-by-step explanation:

20*30=600 units of work

After leave the 5 workers , we have 35 days for complete the work.

In 35 days only 15 workers will do the work.

So the work completed in 35 days by 15 workers = 35 ×15 =525 units

Remaining unit = 600 -525 =75 units

This units would done by 5 workers in ( 75/5) = 15 days

So after 15 days 5 workers should leave the job.
