Assumption method.
Assumed all answer correct, total points score = 20×6=120
Point exceeded = 120-0=120
Each question point difference= 6+4 =10
Therefore, questions answered wrongly=120÷10 =12 questions.
So, questions answer correctly= 20-12 =8 questions.
b) For each number of correct and wrong answered question, the point gain is 6-4=2point
(Example, answered 2 questions with 1 correct and 1 wrong, point gain is 6-4 =2points)
2 points → 2 questions answered.
16 points → 16 questions answered.
Questions not answered = 20 - 16 = 4 questions.
Hope this helps
