There are 100100 questions in a paper.
- Each question carries
+3 marks for correct answer,
-1 marks for incorrect answer i.e. one mark is deducted for each incorrect answer,
0 marks for an unattempted question.
It is given that Chef received exactly �X (0≤�≤100)(0≤X≤100) marks.
Determine the minimum number of problems Chef marked incorrect.
Hi I could only understand a bit from you help request I hope the below program of mine would help you with your problem.
def calculate_incorrect_marks(total_marks, received_marks):
if received_marks > total_marks * 3 or received_marks < 0:
return -1 # Invalid input, marks received exceed the maximum possible or negative
min_incorrect = total_marks # Initialize minimum incorrect marks as the maximum possible
for incorrect in range(total_marks + 1):
correct = total_marks - incorrect
total_received_marks = correct * 3 - incorrect
if total_received_marks == received_marks:
min_incorrect = min(min_incorrect, incorrect)
if min_incorrect == total_marks:
return -1 # No combination of correct and incorrect marks results in the received marks
# Example usage:
total_questions = 100100
received_marks = int(input("Enter the marks received by Chef: "))
min_incorrect = calculate_incorrect_marks(total_questions, received_marks)
if min_incorrect == -1:
print("Invalid input or no combination of marks is possible.")
print("Minimum number of problems marked incorrect:", min_incorrect)
