Number of questions completed
= 80 - 9
= 71
Big difference
= 346 - 232
= 114
Small Difference
= 346 - 340
= 6
Number of wrong answers
= 114 ÷ 6
= 19
Number of wrong and incomplete answers
= 19 + 9
= 28
Number of correct answers
= 80 - 28
= 52
Number of less wrong or incomplete answers than correct answers
= 52 - 28
= 24
Answer(s): 24
