Math Riddles for Class 10: Number Series

Solution

Hopefully, you had fun solving this number series riddle. Now, the time has come to verify your answer.

The missing number in the central circle is 77.

Are you amazed? Don’t worry, you’re not alone. The above riddle was one of the toughest out there, and for good reason.

The numbers in the circle don’t make any sense if you perform the basic arithmetic operations: addition, subtraction, multiplication and subtraction. However, if you think outside the box and use squares, you’ll get the answer in no time.

Here are the steps to reach the solution to this mind-boggling number series riddle.

- Observe the first circle and pair the opposites 3 & 4, and 11 & 7.

- Square the first pair. You get 9 and 16. Now add them together. 9+16 = 25.

- Subtract 7 from 11 and square the result. 11-7 = 4 => 4² = 16.

- Now add the two results of the pairs.

25 + 16 + 41.

- Follow the same process for the second and third circles.

For Circle Three:

4² + 6² + [(12-7)²] = 16+ 36+ 25 = 77

There’s your answer.

Did you get it correct? If so, congratulations.

You’re definitely one of the brightest students in your class. If you failed, don’t lose heart. Keep practising, and you’ll get better with time.
