    Questions are as follows ( not same questions but same type): 


    1. After giving similar type of conditions , what is the element left to H? In this section they gave around 4 matrices of this type and gave some questions for each matrix.


    2. 5’s then which column elements sum equals to 9?


    3. If column1 , Column 4 are interchanged and row3 , row4 are interchanged and diagonal elements from top left to bottom right are written in reverse order then what is the element in row1 and column 1?
