In our real-life, we do come across many practical problems where we have to think out of the box. Sometimes in these

**practical problems, we have to think mathematical**to reach the solution or the problem. Sometimes we have to play detective to solve the mystery. Sometimes these problems related to our knowledge of science or other subjects and sometimes you got an imaginary situation given by your friends and you have to find the solution to these situations.
Here we are putting six such practical problems which you may come across in your daily life. Some of these problems may look difficult to solve and a few of these problems may look impossible to solve. To give your best to solve these problems and try to come up with your answer to each of these practical problems.

These problems have some remarkable solutions which are published at the end. So are you ready to solve these mind blogging practical problems?

Let's start with an easy mathematical practical problem which a father come across during the visit of his son.

__Gold Chain Practical Problem__

__Gold Chain Practical Problem__

I) Once a son is visiting his rich father. His father wanted to gift him gold. However, he doesn't want to fix the amount of gold to be given to his son. So he decides that he will gift his son as many grams of gold as the date of arrival of his son. It means if his son visits him on 1st day of the month, then he will be gifted 1gm of gold. Similarly, in case his son visits him on the 28th day of the month, he will be gifted 28gms of gold. He is having a gold chain which is 31 gms in weight and has 31 parts joined as a long chain. He wanted to keep the gift-ready and so wanted to cut the chain in 31 parts. However, his wise wife suggested that he don't need to cut the chain in 31 parts and still he can manage to get the number as required with very few cuts. Now the question is what are the minimum cuts required to break this chain into so that his desire of giving the number of gold coins is full-filled?

__Gold Chain Practical Problem Solution__

__Gold Chain Practical Problem Solution__

I) This problem can be solved by binary mathematics. He can divide the chain into binary numbers e.g. 1, 2, 4, 8 and 16 which can be achieved with four cuts only. Any number can be formed from 1 to 31 with the combinations of these numbers e.g. 28 can be formed with 15+8+4+1 and 17 can be formed with 16+1 and so on.
