Number of questions completed
= 98 - 6
= 92
Big difference
= 712 - 460
= 252
Small Difference
= 712 - 700
= 12
Number of wrong answers
= 252 ÷ 12
= 21
Number of wrong and incomplete answers
= 21 + 6
= 27
Number of correct answers
= 98 - 27
= 71
Number of less wrong or incomplete answers than correct answers
= 71 - 27
= 44
Answer(s): 44
