Ashok,
There are a couple of errors here:

1. You're using the array reference ( and thus, the entire list) as a key to your hash with a value of 'ashok'. This is backwards. I think (correct me if I misunderstood) you want to use 'ashok' as the key to the hash whose value is the array ref.
2. Change the inner for loop ( I'd use foreach instead, but that's a matter of personal preference) to refelect the changes suggested in (1).

Try this: 

#! /usr/bin/local/perl

use strict;
use warnings;

my $array_ref = [1, 2, 5, 7, 4];

my %hash;
$hash{'ashok'} = $array_ref;

foreach my $as ( keys %hash ) {
    foreach ( @{ $hash{$as} } ) {
        print "$_, ";
    }
}

Hope this helps.
