Bheja Fry question

 It seems a very straight forward question.  

Question 

You have 80 apples. You divide them by half   and add another 30 apples . How many apples you are left with ??

Hint  :  It is not  70  !!!

Answer 

At the first glance ,  we make calculation that

We have 80

Dividing it by half , half of 80 is 40

Then add 30, totally 70 apples !!!

But it is clearly said answer is not   70.

We will again go through question.

It says, we have 80 apples.

Divide them by half  !!!

Here is the culprit.....

We must divide by half, not dividing by 2 !!!

That means,   80   /   ( 1/2  )

==>>   80  *  2  =  160     !!!

Now again add 30 apples.

==>>   160   + 30  =  190  Apples.

Finally we are left with      190   apples  !!!

How flames behave in space ??

 Flames behave differently in space due to microgravity.

Here are the main differences  ----

1.   Spherical shape 

                 Flames tend to be spherical in space as there is no buoyancy or convection to distort their shape.

2.   Slower burning 

                 Flames burn slower and more efficiently in space as there is no oxygen flow to fuel combustion.

3.  No flicker 

                   Flames don't flicker in space as there is no air movement to cause turbulence.

4.  Blue colour 

                    Flames in space often appear blue indicating complete combustion.
