Question

Working together, 20 men of the same capacity can finish a job in 15 days. Now 20 men start together this job but 10 of them leave after 10 days. How many more days will the remaining men take to complete the job?​

Answer 1

Answer:

30 days

Step-by-step explanation:

we know,

work=men*days*hours

Working together, 20 men of the same capacity can finish a job in 15 days.

20 men=1/15 days

Now 20 men start together this job but 10 of them leave after 10 days.

they worked for 10 days

10/15=2/3 work completed

remaining work has to be complete by 10 men in x days

1-2/3=1/3

1/3=10men*x days

x days=1/30
