Answer 1

Can you try using,

var data = $("#vehicleLoan").is(':checked');

OR

    function showDetails(){
               $("#Loan").toggle();
     }

OR

    function showDetails(){
          // debugger;
           var data = $("#vehicleLoan").is(':checked');
           // alert(data);
           if(data)
           {
               $("#Loan").show();
           }
           else
           {
               $("#Loan").hide();   
           }
       } 

Answer 2

try something like this

   if(document.getElementById("vehicleLoan").checked)
   {
       $("#Loan").removeAttr("style","display:block");
   }
   else
   {
       $("#Loan").removeAttr("style","display:none");   
   }
