There are multiple errors in your script.
1. the way you have defined hash

%dbase = { 
        apple => "fruit", 
        brinjal => "vegetable" , 
        coffee => "beverage", 
        };

Using curly braces will create an anonymous hash(a hash reference). You should use parentheses in this case.

2. The return statement should be after the entire processing. Otherwise, in the first iteration itself it will come out of the subroutine.

3. Use "last" instead of "break".

The modified code that works is as below:

%dbase = (
        apple => "fruit", 
        brinjal => "vegetable" , 
        coffee => "beverage", 
        ); 
  
my @info; 
  
$info[0]="lemon"; 
$info[1]="juice"; 
  
$result = validate($info[0],$info[1]); 
  
sub validate 
     { 
        my $usr = @_[0]; 
        my $pwd = @_[1];         
        my $r=0;
        while (($u, $p) = each %dbase) 
            {             
              if ($usr eq $u && $pwd eq $p) 

                    {                       
                      $r=1;
                      last; 
                    } 
              else 
                    { 
$r=0; } 
       }     
  return $r     }     
    
print "$result\n";
