Well First I'll do B- 180/10 = 18 9x18=(180-18)=162 questions correct now A- 200/10=20 20x8.5=170 questions correct so A got more correct (170 correct and 30 wrong) than B (162 correct 18 wrong) but b has less incorrect :P

Which is larger - 200(.85) or 180(.90)? There's your answer, if you just do some basic arithmetic, for who answered the most correct questions. Use the opposite for the other question - which is larger, 200(.15) or 180(.10)?

Student A answered more questions correctly (170) and more incorrectly (30).
