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       !!!!
