List of Tricky Math Questions

We have listed tricky math problems in the following section. See if you can solve the problems before checking the solution.

  • 1. Three Gods Puzzle

As one of the most confusing math questions, this puzzle will hammer your brain cells and logical ability. We consider it The Hardest Logic Puzzle Ever, created by George Boolos, an American philosopher and logician. It was published in 1996 in The Harvard Review of Philosophy journal. Earlier, the Italian newspaper La Repubblica published it. 


Three gods have unique characteristics. One always speaks true, one speaks false, and the other speaks randomly, be it true or false. Determine which god is which. You can ask one yes-no question to each god.

Three Gods Puzzle


Ask any god – "If I were to ask you if you were the truth-teller, would you say yes?" If yes, you can determine the god who speaks the truth. The god who speaks randomly can’t answer the question, and the god who always speaks falsely will answer no.

Later, a computer scientist, John McCarthy, added another difficulty level to this puzzle. Such as,

The gods can understand your question in English, and they will answer in their language, ‘Da’ and ‘Ja,’ for yes and no. But you need to know which means yes and which means no. So, you must find the meanings of ‘Da’ and ‘Ja.’ 


The solution to this tricky math question is to ask each god the same question. The true god will always say yes, and the false god will always answer no. This way, you can determine the nature of the gods.

When you learn to use such complex logic, study time management will become spontaneous. So you can learn math better.

  • 2. Cheryl’s Birthday

This puzzle made all experienced mathematicians stumped when it was first asked in the Asian Schools Math Olympiad contest for 14 to 15 year’s students, which was organized in Singapore in 2015.


Cheryl just became friends with Albert and Bernard. They both want to know Cheryl’s birthday. When they asked Cheryl, she gave them a list of 10 days. 

15th May, 16th May, 19th May, 17th June, 18th June, 14th July, 16th July, 14th August, 15th August, and 17th August.

To give some hint, Cheryl told the month to Albert and the day to Bernard separately. 

Albert said that he doesn’t know Cheryl’s birthday, and he also knows that Bernard does not know her birthday too. Then Bernard replied, earlier, he did not know her birthday, but now he knows. Alber then confirms that he also knows Cheryl’s birthday. 

Now you have to determine which date from Cheryl’s list is correct.

Cheryl's Birthday


On the list of 10 dates, only 19th May and 18th June are unique. The other dates, 14, 15, 16, and 17, come twice. So, May and June go out of the probable list. 

14th July and August cannot be the option as both dates are the same. So any dates between 16th July, 15th August, and 17th August are the correct option. As August has two dates, it is not the birth month. Hence, 16th July will answer this tricky maths question correctly.To solve similar puzzles, you must master the Properties of Operations to strengthen your logical and analytical skills.

  • 3. The Three Ants Puzzle

It is a popular and funny math question of probability for high-school students.  


3 ants are sitting at the 3 corners of an equilateral triangle. Each of them randomly starts moving towards another corner. What is the probability that they do not collide?

The Three Ants Puzzle


The probability of their collision is 1/3. Because if one ant moves clockwise and the other two move counterclockwise, or vice versa, they will not collide. Also, they can never collide if the ants move in the same direction. Check out MyMathlab Answers for such exciting and tricky math questions. 

  • 4. The Monty Hall Problem

An American Statistician, Steve Selvin, first posted this puzzle with the solution in a letter in 1975. Hence, this probability puzzle is named after him. It is a brain teaser influenced by the American television host Monty Hall’s game show ‘Let’s Make a Deal.’ 


In a game show, you have three doors in front of you, and you can select only one out of three. Behind the three doors, two have goats, and the other has a car. You choose door no 1, but the host opens another door with a goat inside it. Now he gives you another chance to change your answer. So, what will you do? Will you stick to ‘door no 1’ or switch to the other door?

The Monty Hall Problem


It would help if you switched to the other door. Because if you change, your probability of winning the car increases to ⅔, which was ⅓ for door no 1. 

Many like the probability for Math Fun Questions because you cannot predict the exact answers.

  • 5. The "Two Trains" Problem

One of the most famous math trick questions is the "two trains" problem. There are several types of "two-train" problems given in school tests. Here, we have provided a general example of this type of problem.


Train X is traveling at 60 mph. It leaves Station A at 9:00 AM. Train Y travels at 40 mph in the opposite direction of Train X. Train Y leaves Station B at 10:00 AM. The distance between Station A and Station B is 300 miles. When do the two trains meet?"

The Two Trains Problem


From the problem, we know that Train X started its journey 1 hour before Train Y. So, within that 1 hour, Train X traveled 60 miles. Since both trains travel opposite directions, we can imagine them moving toward each other. 

So, the combined speed of the two trains is 60 mph + 40 mph = 100 mph. To find out how long it will take for the trains to meet, we can use the formula distance = rate x time. 

The remaining distance from 300 miles is (300-60) = 240 miles.

So the formula will be 240 miles = 100 mph x time,

where time = 240/100 = 2.4 hours.

We calculated the distance when Train Y started its journey at 10:00 AM, and they will take 2.4 hours or 2 hours and 24 minutes to meet. 

Therefore, the two trains will meet at 12:24 PM.
For kids, a hundred chart is indispensable to learn basic math the fun way.
