Number of questions completed
= 96 - 5
= 91
Big difference
= 870 - 438
= 432
Small Difference
= 870 - 852
= 18
Number of wrong answers
= 432 ÷ 18
= 24
Number of wrong and incomplete answers
= 24 + 5
= 29
Number of correct answers
= 96 - 29
= 67
Number of more correct answers than wrong or incomplete answers
= 67 - 29
= 38
Answer(s): 38
