I get the answer key says you passed with a grade of 80, just need an explanation for that please.

Explanation / Answer

Let me know if you have any doubt.

Explanation:

first btnDisplay_Click function will run which will ask grade from the user:

like: What is your numeric grade?
and In question it is given , we are providing response 92.
So, grade =92 will then pass to ShowResult() function.

In ShowResult() function, there are multiple if-else statements which are checking
the conditions to match.

In ShowResult() function, we are calling another function i.e. PassedExam(grade)
which will return true and might updatating the grade marks to 80. Hence,
the result is 'you passed with a grade of 80'.

note: PassedExam() function is not there in your code. So, can't exactly tell
you how grade is become 80.
