a pipe of 20m.a man climb it 5m in a day and slips 2.5m in night. so how much days it will take to climb
To determine how many days it will take the man to climb the 20-meter pipe, we need to calculate the net distance he covers each day.
During the day, the man climbs 5 meters, and during the night, he slips down 2.5 meters. This means that during a 24-hour period, he covers a net distance of 5 meters - 2.5 meters = 2.5 meters.
Since the total distance of the pipe is 20 meters, we can divide the total distance by the net distance he covers in a day:
20 meters / 2.5 meters = 8
Therefore, it will take the man 8 days to climb the pipe.
