After more than 10 days of struggle I was able to find the solution.. well I don't know but the problem is solved with the help of my friend.
We tried many things but finally did nothing much but changed scripts to jquery-1.8.2.js and jquery.SPServices-0.7.2.min.js . It is working fine now.
Here, take a look at this working script.
<script src="/Scripts/jquery-1.8.2.js" type="text/javascript"></script><script src="/Scripts/jquery.SPServices-0.7.2.min.js" type="text/javascript"></script><script type="text/javascript">
$().SPServices.SPCascadeDropdowns({
</script>
Hope this helps someone.
