This code will work even if there is any Phone elements exist for employee:

var emplyees = 
    from emp in emplyeeDetails.Descendants("Employee").Take(10)
    let phones = emp.Descendants("Phone")
    orderby (int)emp.Element("EmpId")
    select new
    {
        Id = (int)emp.Element("EmpId"),
        Name = (string)emp.Element("Name"),
        Sex = (string)emp.Element("Sex"),
        WorkPhone = (string)phones.FirstOrDefault(p => (string)p.Attribute("Type") == "Work"),
        HomePhone = (string)phones.FirstOrDefault(p => (string)p.Attribute("Type") == "Home")                               
    };

Use casting elements to string, int, etc instead of accessing Value property. Why? Because if there is some missing element or attribute in your xml, then you will get a NullReferenceException. But casting will return default value instead. So, code above will parse even xml like this:
