Reply:If it is 80-82 then you need at least a 40 to get a C.
Reply:40 out of 50 for a C at 80%


41 out of 50 for a C at 82%





the math





50 x 0.80 = 40


50 x 0.82 = 41
Reply:You have consider 50 how 100%.


Then:


50 ---- 100 %


x ------ 80 %





I used 80%, because if you get it, you'll get a C.





x = (80 x 50) / 100


x = 4000 / 100


x = 40





Then, you have to get right 40 questions at least, to get a C.
