Hi s_gaurav1091, If I understood your question correctly then here is my try,

$totalNumber = sprintf "%02d", 1;

if($totalNumber =~ /^\d{2}$/){
    if($totalNumber <= 10){
           print "the number is less than 10\n";
    }
}

If you assign two digit integer with preceding zero to the variable then that variable doesn't hold the preceding zero. Since your first condition fails. See below,

$totalNumber = 01;
print $totalNumber;
