 This question was asked on Koun Banega Karodpati program.

Question 

Which chemical element has symbol Po  ??

1.  Phosphorus 

2.  Potassium 

3.  Plutonium 

4.  Polonium 

Answer 

We will look at chemical symbols of each element  

I know phosphorus chemical symbol is  P.

Phosphorus ruled out  !!!

Potassium is having chemical symbol K !!!

Its name came from Latin name Kalium.

Thats why symbol is K.

Potassium ruled out  !!!

Plutonium has chemical symbol Pu.

Plutonium ruled out !!!

Polonium is a very high radioactive element.

Correct answer     POLONIUM   !!!

Bheja Fry Question

 This Bheja Fry question I found when I was browsing internet.

Question 

If          9   +     1     =      64

            8    +     2     =      36

            7     +     3      =      16

Then 

            6     +      4       =     ??  

Answer 

We know 9  +   1   is 10 

but given answer as   64

We know 64 is the square of 8

==>>    9   -    1     =    8    

==>>      8  ^  2      =   64

So, we rewrite    9   -   1    =   64

We know   8   +    2    is      10

But given answer is     36

We know 36 is the square of 6

==>>    8   -  2  =   6  

==>>     6   ^  2  =  36

So, we rewrite    8  -  2   =   36

We know   7  +  3  =  10

But given  7  +  3  =  16

We know 16 is the square of  4

==>>    7  -  3    =    4

==>>     4  ^   2  =   16

So, we write   7  +  3   =   16

Finally        6   +    4    =  ??

We know     6   +   4   is   10

But according to logic it is not the answer  !!!

We know   6  -   4  =   2

==>>   2  ^  2  =  4

So we rewrite      6  +    4   =   4
