This question is actually very simply to answer for smart kids or people who are not bad at math. This is only meant for people who are weak in mathematics or have very bad conceptual knowledge of it. **Generally this question is asked to kids so that they apply their brain and then their concepts of mathematics become stronger since childhood itself**. But you may also ask this to some adult or teenager to check if he/she is smart enough in mathematics or not. So without wasting any more time, here is the question.

# Question:

**What is wrong in the proof shown below?**

1 Rupee (Indian Currency)

= 1 Re

= 100 paise

= 100 p

= 10 p x 10 p

= 1/10 Re x 1/10 Re (since 10 paise = 1/10 Rupee)

= 1/100 Re

= 1 p

= 1 paisa

# Solution:

Now, if you know exactly what is wrong in this proof, you might be thinking that this is very stupid and anyone should be able to figure out what is wrong here. But my friend, such is not the case. Many and many people have such bad concepts of mathematics that they are never able to find what is wrong here all by themselves.

*The thing which is wrong in the proof shown above is that 100 p
is equal to 10 times 10 p
i.e. 10 x 10 p
and not equal to 10 p x 10 p
and therefore the following steps mentioned in the proof are also wrong.*

I would urge you to ask this question to children because when they will not be able to answer this question, you will tell them the answer explaining the concept in deep, and they will remember this concept of math forever!
