Answer 1

 Please have at the following    

 private int GetLargerValue(int num1, int num2, int num3, int num4)
            {
                int largeValue = 0;
                if (num1 > num2)
                {
                    if (num1 > num3)
                        largeValue = (num1 > num4) ? num1 : num4;
                    else
                        largeValue = (num3 > num4) ? num3 : num4;

                }
                else if (num2 > num3)
                    largeValue = (num2 > num4) ? num2 : num4;
                else
                    largeValue = (num3 > num4) ? num3 : num4;

                return largeValue;
            }
