A test contains 50 multiple choice questions. Suppose that one gets 2 marks for every correct answer. However, for every incorrect answer or unattempted question, 1 mark is deducted from the student’s score. If Rama’s score on this test is 58, find the following: The number of questions she attempted correctly: The number of questions she attempted incorrectly or left unattempted:

Answer 1

Answer:

42

Step-by-step explanation:

Given, Test total question = 50

Each of Mark's = 2

Therefore, Total Mark's = 50 × 2 = 100

If answer is incorrect or unattempted Mark's will be reduced by = 1

And, Rema got = 58/100 (58 out of 100)

Percentage of Rema = 58 %

There fore, Total incorrect or unattempted questions are

= Total questions - correct answers

= 100 - 58

= 42

Hence, 42 incorrect or unattempted number of questions she attempted.
