B.9
Answer:
(a). 24
(b). 0 (zero)
Step-by-step explanation:
(a). Mithun attempt questions = 9
Total score = 9×4
= 36
Total wrong questions = 6
each wrong questions get = -2
total = 6×(-2)
= -12
= 36+(-12)
= 24 marks he get
(b). His friend attempt questions = 5
Total score = 5×4
= 20
Total wrong questions = 10
each wrong question get = -2
= 10×(-2)
= -20
= 20+ -20
= 0 Answer.
