How i can make changes in my totalamount rate values (addition with 10rs) by changing some of my input fields as night,rooms,adult,child & child age in php codeigniter. I just add total amount field for consideration.

You may use jQuery for that purpose

$("#mymodalrooms").on("change",function(){
    if($("#mymodalrooms").val()==="3"){
        $("#totalamount").val(parseInt($("#totalamount").val())+10);
    }
});

Add jquery to add value in amount. You can use on change event for this.

$(document).on('change', '#mymodalnationality, #mymodalrooms, #mymodaladult, #mymodalchildren, #mymodalchildrenage', function(){
      var amount = $('#totalamount').val();
      amount = parseInt(amount) + 10;
      $('#totalamount').val(amount);
   });
