First of All you need to create a model

public class LINQDATA2
    public Int64 SID { get; set; }
    public Int64 RID { get; set; }
    public string Schema_Name { get; set; }
    public string SType { get; set; }
    public string InvestmentType { get; set; }
    public int Allocation { get; set; }
    public int Lum_Sum_Amount { get; set; }
    public float Total { get; set; }

Because dynamic column is not possible in LINQ.

Now perform query like

var x = data.Select(i => new LINQDATA2 { SID = i.SID, Total = (i.Allocation / 100) * i.Lum_Sum_Amount }).ToList();

and pass this model to partial view
