Answer:
(i) Anil gets 6 correct answers = 6×4
= 24
He gets 4 incorrect answer = 6×(-2)
= (-12)
Total Score = 24-12
= 12 marks
(ii) Sunil gets 5 correct answers = 5×4
= 20
He gets 5 incorrect answer = 5×(-2)
= (-10)
Total Score = 20-10
= 10 marks
(iii) Rahul gets 1 correct answer = 1×4
= 4
He gets 3 incorrect answer = 3×(-2)
= (-6)
Total Score = 4-6
= (-2) marks
