In real life, we do come across many practical problems where we have to think out of the box. Sometimes in these Critical Thinking Practical Problems, we have to think mathematically to reach the solution or the problem. Sometimes we have to play detective to solve the mystery. Sometimes these problems are 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 this situation.

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 that a father comes across during the visit of his son.

__Gold Chain Critical Thinking Practical Problem__

__Gold Chain Critical Thinking 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 28 grams of gold. He is having a gold chain that 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 into 31 parts. However, his wise wife suggested that he doesn't need to cut the chain into 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 fulfilled?

II) Detective Sherlock Homles reviewed the information they had on the case so far. A lady was found shot and they already had a list of suspects - Tom, Harry, Harsh, Aaron, and Robinson. Plus, there were five notes that were found that were from the killer.

The first was found at the harbor.

The second was found in an art studio.

The third was in a restroom.

The fourth is in a supply room. and

The fifth in a house.

All of the notes read the same thing, "The clues are where you find the notes." Yet, nothing was found at any place the notes were.

Taking one more look at all the clues, Detective Sherlock immediately solved the case.

III) An absentminded philosopher forgot to wind up the only clock in his house. He had no radio, television, telephone, internet, or any other means of ascertaining the time. He, therefore, decided to travel on foot to his friend's house, a few miles down a straight desert road. He stayed there for the night and when he came back home the following morning, he was able to set his clock to the correct time. Assuming the philosopher always walks at the same speed, how did he know the exact time upon his return?

Note: this is not a trick question. The Philosopher did not bring anything to his friend's house, nor did he bring anything back with him on his trip home.

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.

III) This is simple, he knows the time at which he left his house. Then when he reached his friend's house, he notes down the time to reach his friend's home. As he always walks at the same speed, he will take the same time for returning home from his friend's house. So he notes down the time at his friend's house before leaving his friend's house. After reaching his house he adds his time of travel to his noted time and then fixes his clock.

V) The family will cross the river in the below-mentioned steps

1. Both children go to the other end.

2. One child comes back

3. One of the parents goes to the other end.

4. Another child comes back.

With this now one adult is transported to the other end of the river.

Repeat steps 1 to 4 to transport another adult to the other end of the river.

Now both the parents are on the other side of the river.

Repeat steps 1 to 4 again to transport the fisherman also to the other end.

Now all 3 adults have crossed the river and the children are on the other side.

In the last step, both children cross the river and hand over the boat to the fisherman. The fisherman now rows it back to the other side. With this full family crossed the river.
