Question

In the competitive examination 5 marks are awaded for every correct answer ,2 marks are deducted for every wrong answer and 0 mark is given for not answering a question. Find the score of a boy who attempts all questions (20) but only 12 answers are correct.

Answer 1

Answer:

44 marks

Step-by-step explanation:

For correct answer, marks = 5

For incorrect answer, marks = -2

For not attempting, marks = 0

If a child attempts all 20 and only 12 are correct, then no. of incorrect answers = 20-12 = 8.

Thus, his marks = 12(5) + 8(-2) = 60 - 16 = 44.

Hence, he gets 44 marks.
