Question

30 men working 5 hours a day can do task in 16 days ​

Answer 1

Answer:

If 30 men work 5 hours a day for 16 days,then we can say that 30 men worked for total (5x16) 80 hours. Therefore it took (30x80) 2400 man-hours to complete the task.

Now we have 40 men available, ready to work for 6 hours a day. Therefore

40x6xno of days =2400 man hours

No of days=10.
