Question

In a class test containing 15 questions, 4 marks are given for every correct answer and 2 marks are deducted for every wrong answer. Anu attempted all the questions but only 7 of his answers were correct. What was his total score?

Answer 1

Answer:

Toral marks of Anu = 24

Step-by-step explanation:

Let's gather the data required from the data given.

There are 15 questions in a class test.

4 marks were awarded for every right answer and 2 marks were cut for every wrong answer.

Anu attempts all 15 questions but succeeds in getting 9 correct answers only.

Solution:

The marks awarded for a right answer is 4 marks.

So, for 9 right answers she gets 4(9) = 36 marks.

The marks deducted for every wrong answer is 2.

So,for 15 - 9 = 6 wrong answers -2(6) = -12 marks are deducted.

So, now her total marks are 36 + (-12) = 24.

Therefore, Anu scored 24 marks.
