Ask what type of values can be passed to Grade function.
If its in string format, then we need to Parse the values to Int.
If its a string format, then it can be null or empty or can have spaces in between.

Test data to test function Grade(ObtainedMarks, TotalMarks):
1. Boundary conditions.
Test each individual grades for their boundary conditions.
i.e MarksObtained = 0, 40, 41, 60, 61, 80, 81 and 100, assuming that TotalMarks = 100.
If total marks != 100, then change the values to test those Percentages.

2. Negative conditions.
MarksObtained = -10, total marks = 0.
This will cause divide by Zero Exception.

3. Invalid conditions:
Marks obtained = 110. Total Marks = 100.
Passing alphanumeric or special characters.

4. All possible combination of numbers of a number scale. i.e negative values, zero and positive values for both the parameters, MarksObtained and TotalMarks.

var obtainedMarks = 20;
            var totalMarks = 40;
            var gradeCalculation = 100*(obtainedMarks/totalMarks);
            var result = string.Empty;

            if (gradeCalculation >= 0 && gradeCalculation <= 40)
            {
                result = "D Grade";
            }
            else if (gradeCalculation >= 41 && gradeCalculation <= 60)
            {
                result = "C Grade";
            }
            else if (gradeCalculation >= 61 && gradeCalculation <= 80)
            {
                result = "B Grade";

            }

                result = string.Empty;
