all the logic for this lies in the query

your query should be
List<Account> accList = [SELECT Name, (SELECT Name FROM Contacts) FROM Account];

Hi pandey,

change the vf page like this.......and don't change the controller
Visualforce page::::::::::

<apex:page sidebar="false" controller="wrapper2">
<script>
        function checkAll(c)
        {
            var inputvar = document.getElementsByTagName("input");
            for(var i=0; i<inputvar.length; i++)
            {
                if(inputvar[i].id.indexOf("selec")!=-1)
                inputvar[i].checked = c.checked;
            }
        }
    </script>
<apex:form >
<apex:pageBlock >      
<apex:pageBlockSection columns="2">
 <apex:pageBlockTable value="{!wrapaccountlist}" var="waccl" id="block1">                 
   <apex:column >
   <apex:facet name="header">
   <apex:inputCheckbox >
   <apex:actionSupport event="onclick" action="{!ProcessSelected}" reRender="pt,block1" onsubmit="checkAll(this)"/>          
          </apex:inputCheckbox>             
           </apex:facet>                                          
       <apex:inputCheckbox value="{!waccl.isSelected}" id="selec">
      <apex:actionSupport event="onclick" action="{!ProcessSelected}" reRender="pt,block1"  />                      
       </apex:inputCheckbox>         
   </apex:column>            
    <apex:column value="{!waccl.accn.name}"/>
    <apex:column value="{!waccl.accn.phone}"/>
    <apex:column value="{!waccl.accn.billingcity}"/>
 </apex:pageBlockTable>
 <apex:pageBlockSection columns="1" >
  <apex:pageBlockTable value="{!selectedAccounts}" id="pt" var="sa" >
    <apex:column value="{!sa.LastName}"/>
   </apex:pageBlockTable>
</apex:pageBlockSection>
</apex:pageBlockSection>
</apex:pageBlock>

account -  fld-Total sal-intger r currncy

contact -fld  -sal of cntct-intger r currncy

when ever we create cntct  and sal is added in the field all cntct sal of total should be updated in account total sal field

Task-ex: if we have 5 cntcts of sal(10.000,25.0000,55.444,22.000,77.0000) while creating f recrd and updatng the recrd in sal fld in cntcts
it should be total in accnt fild total sal.?
