You may want to try something like below.

Data Set

<Root>
<data>
<office>Mumba</office>
<officeId>1JC9FJBM</officeId>
<customer>
    <custName>Yash</custName>
    <pirmaryCustCheck>true</pirmaryCustCheck>
    <id>8</id>
  </customer>
<customer>
  <custName> Rahul</custName>
    <pirmaryCustCheck>false</pirmaryCustCheck>
    <id>9</id>
  </customer>
 </data>
 <data>
<office>Mumba</office>
<officeId>1JC9FJBM</officeId>
<customer>
    <custName>Yash</custName>
    <pirmaryCustCheck>false</pirmaryCustCheck>
    <id>11</id>
  </customer>
<customer>
  <custName> Rahul Jain</custName>
    <pirmaryCustCheck>false</pirmaryCustCheck>
    <id>10</id>
  </customer>
</data>

Code -

string pathd = @"C:\Users\admin\documents\newCust.xml";

        XDocument docss = XDocument.Load(pathd);

        var customerTrue = docss.Descendants("data").Elements("customer").Select(x => x).FirstOrDefault();
        var customerFalse = docss.Descendants("data").Elements("customer").Select(x => x).LastOrDefault();

        var records = docss.Descendants("data").Select(x => new
        {

            office = (string)x.Element("office"),
            officeId = (string)x.Element("officeId"),
            customer = new
            {
                custName = (bool)x.Elements("customer").First().Element("pirmaryCustCheck") ? (string)x.Elements("customer").First().Element("custName") : (string)x.Elements("customer").Last().Element("custName"),
                pirmaryCustCheck = (bool)x.Elements("customer").First().Element("pirmaryCustCheck"),
                id = (bool)x.Elements("customer").First().Element("pirmaryCustCheck") ? (string)x.Elements("customer").First().Element("id") : (string)x.Elements("customer").Last().Element("id")
            }
        }).ToList();

var customers = (from e in docss.Descendants("data").Elements("customer")
                         where (bool)e.Element("pirmaryCustCheck") == true
                         select new 
                         {
                             Name = (string)e.Element("custName"),
                             Id = (string)e.Element("id"),
                         }).ToList();
