Bheja Fry question

 This Bheja Fry question I came across on Internet.

Question 

If          92  +  3  =  73

              75   +  2  =  22

              84  +  3  =  43

Then       97  +  1  = ??

Answer 

There are total 5 columns of numbers in the question.

If we see closely, the number of  3rd column has been repeated as the same number fifth column  !!!!

Look at first row,       92  +  3   =  73

The number 3 which is at 3 and 5 column is same.

In the remaining row also, it is repeated.

Now look at numbers at columns 1, 2 and  4.

The number at column 4 is the subtraction result of numbers in column 1 and 2   !!!!

Same thing with remaining rows  also.

Like   75 +  2  =  22

             84  + 2  =  42

Combining all these facts, we can conclude 

               

                      97  +  1   =  51       !!!!

Surprising facts about Caspian Sea

  Caspian Sea appears as a ocean stretching endlessly to the horizon.

Yet, scientists classify it not a sea but as Earth's largest lake  !!!

It surpasses Japan in size.

It borders   Russia    

                       Azerbaijan 

                       Kazakhstan 

                       Turkmenistan 

                       Iran 

It is one of the world's captivating geological wonders.

However it is not a typical lake.  

Its waters arrive chiefly via rivers especially river Volga which supplies 80% of inflow.

Caspian Sea hosts unique species found nowhere else on Earth.

This place has an airport runway crossing a public road !!!!

 Airport runways rarely intersect with roads.

Strict security is ensured for clear separation.

But here, active runway of international airport cuts directly across the main road into the city  !!!

Every time a plane lands or takes off, cars and pedestrians must stop.

This airport sits between the sea and the Rock leaving little room for expansion.

As the result, runway cuts straight across the main road  !!!

When a plane is about to land or take off, traffic lights turn red and barriers come down as every one wait patiently as aircraft roll past.

Country is

                       GIBRALTAR     !!!

Birds that produce milk !!!

  The animals who feed their young ones are referred as mammals.

Except bat, none of the birds are classified under mammals.

That means birds don't breast feed their children   !!!!

But there are handful of birds that are evolved to produce a substance known as crop milk  !!!

Crop milk is not the milk similar to the milk mammals produce.

Crop milk is a nutrient rich secretion produced from the lining of crop  which is a pouch in throat area.

Despite its name, crop milk is not a true milk but a secretion rich in proteins and fats.

Here are the special birds which produce crop milk   -----

1.   Pigeons 

2.  Doves

3.  Flamingos 

4.  Emperor penguins
