Answer:
All are 'a'
i. a
ii. a
iii. a
iv. a (options are incorrect it should be -16 not 16)
v. a
Step-by-step explanation:
__________________________________________________________
i. Guru answered all questions but 8 only correct.
Marks for a correct answer = 4
Marks for a incorrect answer = -2
He scored = 8 x 4 = 32
__________________________________________________________
ii. Siri answered all questions but 6 are wrong.
Marks for a correct answer = 4
Marks for a incorrect answer = -2
She scored = 6 x -2 = -12
__________________________________________________________
iii. Reva answered all questions and her score is 34.
Marks for a correct answer = 4
Marks for a incorrect answer = -2
She answered all questions and only 1 incorrect, means he scored other questions correctly so 10 - 1 = 9
She answered 9 questions correctly
__________________________________________________________
iv. Jay answered all the questions he got 2 correct answers.
Marks for a correct answer = 4
Marks for a incorrect answer = -2
Total questions answered by Jay = 10
He answered got only 2 correct, means remaining 8 are incorrect,
Jay got marks for incorrect answers = 8 x -2 = -16
__________________________________________________________
Aarav's score is 0,
because only 0 is a number which is neither positive nor negative.
