​

Answer 1

Step-by-step explanation:

ATQ ,

total mark = 25 ×4 = 100

he corrected 20 questions ,

for every correct answer he got 4 marks

so 20× 4 = 80 marks

& for every wrong answers 2 marks will be deducted,( he answered 5 questions wrong)

so , 5× (-2) = -10

total mark obtained = 80-10 = 70

hence,

total score = 70/100
