A man fell in a 50m deep well. He climbs 4 meters up and slips 3 meters down in one day.
How many days would it take for him to come out of the well?
The man would take 47 days to come out of the well.
On the first day, the man climbs 4 meters up and slips 3 meters down, therefore he only climbs 1 meter up per day.
On the 46th day, he would have climbed 46 meters. On the 47th day, he would climb 4 meters to reach the top (46 + 4 = 50 meters) of the well, thereby completing his task.
He will no longer slip from the well as he is already out of the well after completing his task.
