There were a total of 66 questions in a school Maths test. 10 marks were awarded for each correct answer and 7 marks were deducted for each incorrect answer or incomplete answer. Lynn could not complete all the questions in time and left the last 13 questions blank. She scored 167 marks. How many more correct answers than wrong or incomplete answers did she answer?

Correct answers	Marks awarded (x10)	Wrong or incomplete answers	Marks deducted (x7)	Difference
53	530	13	91	439
52	520	14	98	422

Number of questions completed
= 66 - 13
= 53

Big difference
= 439 - 167
= 272

Small Difference
= 439 - 422
= 17

Number of wrong answers
= 272 ÷ 17
= 16

Number of wrong and incomplete answers
= 16 + 13
= 29

Number of correct answers
= 66 - 29
= 37

Number of more correct answers than wrong or incomplete answers
= 37 - 29
= 8

Answer(s): 8
