DATA MATRIX

              Col 1  Col 2  Col3  Col4
Row 1        @     %       $       #
Row 2        %     +        #       &
Row 3        @      &        %      #
Row 4        *       +        $       &

Interchange Row3 with col3 , Row1 with Row4 and reverse the diagonal elements from top left to bottom right:

Quest: which is the 4th element of row2;
Quest: which is the second diagonal element from top;

NOTE: change in the matrix is applied only for the particular questions only , it is not reflected in to another question.
