Please find the code below

#!/usr/bin/perl
use strict;
use warnings;

use IO::All;
use Data::Dumper;

my @lines = io('test_Scores.txt')->chomp->slurp;
splice @lines, 0, 1; # remove first line

my %hash;
foreach my $line (@lines) {
    $line =~ s/^\s+//;
    my @elements = split /\s+/, $line;  
     my $key = join '-',splice @elements, 0, 2;      
    $hash{$key} = \@elements if length($key) > 0; 
   
}
print Dumper \%hash;

i am gettingvar$1={'apple-A'=>['30','40','50','60']}

That is the default Data::Dumper format. Use either

$Data::Dumper::Useqq = 1;
print Dumper \%hash;

or dump the values as your original post.

for my $key (sort keys %hash) {
  printf "%-12s %s\n",$key,join ' ',@{$hash{$key}};
}

hi poj,the two lines of code are not working

How to get rid of the single quotes for the values 30,40,50,60

Data::Dumper is a debugging tool, I would not use it to get consistently formatted output. Because Perl transparently converts between strings and numbers, 30 and "30" are practically the same thing, and so modules such as Data::Dumper have to more or less "guess" in which format to output such values. This kind of question actually comes up often when serializing Perl data structures, and usually the solution ends up being some custom code (one example: Cpanel::JSON::XS::Type).

So I guess the question is, why do you need the output in this format, and could you give a longer specification of the expected output format?

Hi haukex,actually i want the data in below format

 $var1 ={apple-A =>[30,40,50,60]}

because i have to achieve the average of it as well, once the output is in that format.one of the reason is i was instructed to do achieve output in that way.
