Solve the following riddle.
Tell me who I am
I shall give a pretty clue!
You will get me back
If you take me out of twenty two!

Hint: Consider the required number as ‘x’. It is given that if ‘x’ is taken out of 22 you will get it back or the result will be the same i.e. ‘x’. Solve the equation $22 - x = x$ to find the value of ‘x’.


Complete step-by-solution:
We are given a riddle which states that, if a number is taken out from 22, then you will remain with the same number.
Let the number be ‘x’.
Take out the number ‘x’ from 22, $22 - x$
The result of $22 - x$ will again be ‘x’
$22 - x = x$
Send ‘x’ to the RHS
$
  22 = x + x \\
  2x = 22 \\
  x = \dfrac{{22}}{2} \\
  x = 11 \\
 $
Therefore, when we remove a number ‘x’ from 22 the result will be the same number ‘x’ and the number is 11.
$22 - 11 = 11,2 \times 11 = 22$ This shows when you take out 11 from 22, 11 will remain.
Additional Information: Riddles increase the production of dopamine in our body, a neurotransmitter that enhances mood, memory, and concentration. Riddles for kids can also increase the thinking ability and creativity.


Note: 22 is an even number. So if a number is taken out from it and the result is the same number then the number must be odd. Be careful with the result you get.
