Question

In a class test containing 15 questions, 4 marks are given for every correct answer and
(-2) marks are given for every incorrect answer. (i) Bharathi attempts all questions but
only 9 answers are correct. What is her total score? (i) One of her friends Hema attempts
only 5 questions and all are correct. What will be her total score?​

Answer 1

Answer:

(I) 9 answers are correct so score is 9×4 =36

and 6 are wrong so 6×-2=-12

so score is 36+(-12)=36-12=24

(ii) 5 questions are correct so score is 5×4=20

so score is 20
