Question

you have a rod of length 7 and you have to give a part of rod of length of one everyday to a person. so what is the minimum number of cuts you will do so that you can give him required number of lengths everyday?

Answer 1

There is a 7 unit of length rod and you are distributing 1 unit daily.

On 1st day you will cut one and then 6 will left

On 2nd day you will cut one and then 5 will left

On 3rd day you will cut one and then 4 will left

On the 4th day you will cut one and then 3 will left

On the 5th day you will cut one and then 2 will left

On the 6th day you will cut one and then 1 will left

On the 7th day you don’t have to cut it.

Hence, there is a total of 6 cuts.
