Answers
Answer:
30
Step-by-step explanation:
Total questions = 15
Every correct answer = +4
Every wrong answer = -1
Divya's total correct answers = 9
Marks for the correct answers = (9 x 4) = 36
Divya's total wrong answers = (15 - 9) = 6
Marks deducted for the wrong answers = (6 x -1) = -6
Total marks obtained by Divya = 36 + (-6)
or, 36 - 6
= 30
Given : Test containing 15 questions
4 marks are given for every correct answer and (-1) mark is given for every wrong answer
Divya attempts all the questions but only 9 of her answers are correct
To Find : Her total score
Solution:
Total Question = 15
Attempted = 15
Correct answers = 9
Incorrect answers = 15 - 9 = 6
Mark for 1 correct answer = 4
Marks for 9 correct answers = 4 * 9 = 36
Mark for 1 incorrect answer = -1
Marks for 6 incorrect answers = -1* 6= -6
Total score = 36 - 6 = 30
Hence her total score = 30
