Answer:

Explanation:

a) Out of 5, 1 only one is wrong. So number of questions answered correctly is (4/5)

To find the percentage, multiply (4/5) by 100

$\sf (4)/(5)*100 = 4* 20 = 80 \%$

b) It is not possible to find the actual score because we don't know how many questions were there actually and the score for each question.
