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
