Are you good enough at math? Remember your school days. What did you usually do in math classes? These math riddles will help you know where you stand!
Mathematics is a subject known for breaking friendships. Walk into a classroom where all the kids are happily working and playing and you’ll find a strangely competitive vibe at the math conference. Mathematics divides the classroom into three sections: the experts of the Archimedean level, the zealous of the first type, and those who scribble masterpieces in their notebooks.
The first type are those who are even more prepared than the teachers. They work day in and day out just to get the right value of “x.” Whether it’s menstruation or geometry, they are the Mozarts of all trades. These students may forget to bring their water bottles or lunch to school, but not their math textbooks.
The second section of students wants to be like the first type, but they would never admit it. These are in constant rivalry with the first section that knows nothing less than pure excellence. These people don’t work as hard as the first type of students, but they still try hard and fail sometimes, but they manage to get the right answers once in a blue moon.
The third section is the most interesting. These students went to great lengths to miss the math lecture. These are the artistic types. Not many teachers admire his art, but they don’t let his morale drop. Check their math notebooks and you’ll find red marks, incorrect answers, and incomplete sums. Turn the notebook over and look from the back and you’ll find Picasso-level pieces of art. These people are not very interested in algebra, equations and numbers; His vivid imagination breaks the walls of math classrooms. Believe it or not, the best musicians, poets, rappers and artists are born in math classes.
Now, whether you were in the first category, the second category, or the third is a completely different debate. You assign your position yourself. What we are going to do today is recapture your childhood days and test your mathematical acumen in reality.
Wondering how?
We present to you a set of 3 exciting mathematical riddles that would be enough to test your waters.
Are you ready? Relax your beating heart, we are not as strict as your math teachers at school!
Mathematical riddle 1:

Mathematical riddle 3:
A number is divided into two parts, so that one part is 10 more than the other. If the two parts are in the ratio 5:3, find the number and the two parts.
This seems easy, but many fail to find the correct answer. Can you master them all?
Take your time if you want. Grab a notebook and a pen that works. Hey… you better not call your math teacher for help!
Could you do it right? Here are the answers!
Mathematical riddle 1:
The sum of the two numbers is 25. One of the numbers exceeds the other by 9. Find the numbers.
ANSWER 1:
Let the number be x.
We know that the other number is x+9.
Sum of two numbers = 25
According to the question, x + x + 9 = 25
⇒ 2x + 9 = 25
⇒ 2x = 25 – 9 (by bringing 9 to the right side it changes to -9)
⇒ 2x = 16
⇒ 2x/2 = 16/2 (divide by 2 on both sides)
⇒ x = 8
Therefore, x + 9 = 8 + 9 = 17
Therefore, the two numbers are 8 and 17.
Mathematical riddle 2:
The length of a rectangle is twice its width. If the perimeter is 72 meters, find the length and width of the rectangle.
ANSWER 2:
Let the width of the rectangle be x,
Therefore, the length of the rectangle = 2x
The perimeter of the rectangle = 72
Therefore, according to the question
2(x + 2x) = 72
⇒ 2 × 3x = 72
⇒ 6x = 72
⇒ x = 72/6
⇒ x = 12
We know that the length of the rectangle = 2x
= 2 × 12 = 24
Therefore, the length of the rectangle is 24 m and the width of the rectangle is 12 m.
Mathematical riddle 3:
A number is divided into two parts, so that one part is 10 more than the other. If the two parts are in the ratio 5:3, find the number and the two parts.
ANSWER 3:
Let x be a part of the number.
Then the other part of the number = x + 10
The ratio of the two numbers is 5:3.
Therefore, (x + 10)/x = 5/3
⇒ 3(x + 10) = 5x
⇒ 3x + 30 = 5x
⇒ 30 = 5x – 3x
⇒ 30 = 2x
⇒ x = 30/2
⇒ x = 15
Therefore, x + 10 = 15 + 10 = 25
Therefore, the number = 25 + 15 = 40
The two parts are 15 and 25.
So friends, where are you?
Are you the Archimedes type, the competitive type, or the doodling type?
