Try something like this:

            dataGridView1.Rows.Add("Mark",11,15,14,0);
            dataGridView1.Rows.Add("John", 10,15,13,0);
            foreach (DataGridViewRow row in dataGridView1.Rows)
            {
                int total = 0;                                    
                foreach (DataGridViewCell c in row.Cells)
                {
                    if (c.Value != null)
                    {
                        if (c.ColumnIndex != 0 && c.ColumnIndex != 4)
                        {
                            total += Convert.ToInt16(c.Value);
                        }
                        else if (c.ColumnIndex == 4)
                        {
                            c.Value = total.ToString();
                        }
                    }    
                }                     
            }
