Example to Percentage to Grade Conversion:

Example 1:

John scored the marks in five subjects 87, 90, 88, 76 and 65. The test is conducted for 100 marks in each subject. Find the grade of the john.

Solution:

Total marks of the test = 5 `xx ` 100 = 500

Total marks of the john = 87 + 90 + 88 + 76 + 65 = 406

Percentage of the marks scored by john = `406/500` `xx` 100 = 81.2% or `81.2/100` = .812

Therefore john got B grade


Example 2:

Martin scored the marks in five subjects 85, 95, 65, 75 and 55. The test is conducted for 100 marks in each subject. Find the grade of the Martin.

Solution:

Total marks of the test = 5 `xx` 100 = 500

Total marks of the Martin = 85 + 95 + 65 + 75 + 55 = 375

Percentage of the marks scored by Martin = `375/500` `xx` 100 = 75% or `75/100` = .75

Therefore Martin got B- grade
