for(var abc=1;abc<3;abc++)
{
    $('#whereEntry').delegate(".income_count"+abc, 'change', function ()
       {
           var incomeValue = $(this).val();
           var sum = 0;
           $('#whereEntry').find('.reduce_count'+$(this).attr('index')).each(function (){
               sum += Number($(this).val());
           });
         $('#finale'+$(this).attr('index')).val(incomeValue - sum);
    });


    $('#whereEntry').delegate(".reduce_count"+abc, 'change', function ()
{
   
    var incomeValue = $('#whereEntry').find('.income_count'+$(this).attr('index')).val();
    var sum = 0;
           $('#whereEntry').find('.reduce_count'+$(this).attr('index')).each(function (){
               sum += Number($(this).val());
           });
    $('#finale'+$(this).attr('index')).val(incomeValue - sum);                           
                                         
});

}     
    });
