Answer:
i) 8
ii) 20
Step-by-step explanation:
i) Total Marks scored = 36
Total Right answers = 12
Total Marks from right answers = 12×5=60
ATQ
Marks from right answers - Marks deducted from Wrong answers = Marks Obtained
60-x=36
x=24
Now number of wrong answers = Total marks deducted from wrong answers / Marks deducted per wrong answer
= 24/3
= 8
ii) Marks for Correct Answers = 10×5 = 50
Marks Deducted for wrong answers = 10×3 = 30
Marks Scored = 50-30 = 20
