gram panchayat decides to construct a road in a village. the contract etimates that 25 people can complete the constructin in 24 days. but 5 more people join. how long will they take to complete the job?

20 days

Step-by-step explanation:

If the number of man-days is constant, the time required is inversely proportional to the number of workers. That means 6/5 as many people should be able to do the work in 5/6 as many days:

(5/6) (24 days) = 20 days
