Answer:
32,6
Step-by-step explanation:
No : of correct answers =9
Marks for every correct answer =6
Therefore marks for 9 correct
answer=9×6=54
No: of incorrect answer= 11
Marks for every incorrect answer =-2
Therefore marks for 11 incorrect answer =11×-2=-22
Total marks= 54+-22=32
Summit problem
Total marks =36
No:of correct answer =8
marks for 8 correct answer = 8×6=48
Marks lost due to incorrect answer=48-36=12
Marks for incorrect answer =-2
No:of incorrect answer=12÷-2=-6
since number cannot be negative answer is 6.
Thanks
