Like the muscles of the human body, the brain also needs training to perform well and stay in shape.
And there is nothing more stimulating and more effective for perfecting the functioning of your brain than mental exercises like the one we have prepared for you below.
This is a IQ test in the form of a brain teaser mathematical. It will test your critical thinking, your logical-mathematical skills as well as your speed of analysis and problem solving. It’s a complete workout for those who know how to take advantage of it.
Math test: “Find the value of each shape to deduce the solution to the last equation”
The following image has 4 equations whose unknowns are represented by different geometric shapes. The last equation is not yet solved. Your challenge then is to find the answer to this fourth equation.
As you will have understood, you will not take on this challenge without successfully completing an additional task upstream: finding the value of each shape. Only once this step has been taken can you solve the equation: 1 round + 1 square x 1 rod = ?
To achieve this, you will need to tap into your imagination and use an unconventional problem-solving method. Are you ready ? It’s up to you !
IQ test: The correct answer
If you are unable to solve this mathematical riddle, you can find the solution below:
The solution
The answer to the last equation is 7. To find this answer, here is the logic you had to follow:
In the first equation, you get the value of the square = 2.
Then in the second equation, you have that of the triangle by introducing the value of the square: 3.
Then the value of the circle is obtained with the third equation: 1.
Then, simply calculate the last equation while respecting the order of priority of calculations in mathematics which goes as follows: 1 + 2 x 3 = 1 + 6 = 7.
Remember that mathematical exercises like this stimulate the brain enormously. They develop your logical-mathematical skills, your critical sense, your concentration and your speed of thinking.
These IQ tests are then perfect for keeping your brain in good shape while having fun. Find the best brain challenges on our site and don’t hesitate to invite your friends and families to stimulate their intelligence with you!
