What you will need to do is to bind the .hover() function outside of the click event, not inside it:

$(document).ready(function() {
    $('.parent').click(function(e) {
        e.preventDefault();
        indexn = $('.parent').index(this);
        $('.chaild:eq(' + indexn + ')').show();
    });
    $('.parent ul li').hover(function() {
        $(this).toggleClass('selected');
        var liIndex = $(this).index(),
            parentIndex = $(this).parents('.parent').index();
        $('.chaild:eq('+parentIndex+') > ul > li:eq('+liIndex+')').toggleClass('selected');
    });

});
