Answer:
1. 10 questions were correct and the Mark's awarded for each correct question = 5
Mark's awarded = 50
No. of questions wrong = 20-10 = 10
Negative Mark's for each question = -2
Total Mark's deducted = -20
Total makes a student scored = 50 - 20 = 30 Mark's
2. 5 questions were correct and the Mark's awarded for each correct question = 5
Mark's awarded = 25
No. of questions wrong = 20-5 = 15
Negative Mark's for each question = -2
Total Mark's deducted = -30
Total makes a student scored = 25 - 30 = -5 Mark's
