ans.   X(1,1)=3000 (given)

Each element occupies 4 bytes of memory so

           X(1,2)=3004

           .

           .

            X(1,7)=3042

             X(2,1)=3046

              .

               X(2,7)=3052

                X(3,1)=3056

................X(3,7)=3080

             X(4,1)=3084

   .........X(4,7)=3108

             X(5,1)=3112

.............X(5,7)=3136

              X(6,1)=3140

...............X(6,7)=3164

                X(7,1)=3168

.................X(7,7)=3192

                  x(8,1)=3196

...................X(8,5)=3212-----------ans

<base-addr> + <element-size>[max.cols*(x-1)+(y-1)]
here base-addr =3000
elt size = 4
max-cols  =7  --> 9x7
x=8
y=5
==>
3000 + 4[7*(8-1)+(5-1)] =3212

4) Just solve the following simultaneous equations:

if the number we are after was XY, then:

3/4(Y)+X=10
Y+1/4(Y)=10-1

X=4, Y=8

Formula:
Base address+byte required{N(i-1)+(j-1)}
Here Base addres is 3000.
          Byte required is 4.
          N=Number of columns in an array.
           i=row of the array element of the address to be found.
           j=column of the array element of the address to be found.
Solution;
         3000+4{7(7)+4}=3212.
