Question

Ruchi scored 20 marks.If she has got 12 correct answer,How many question has she attempted incorrectly?​

Answer 1

Answer:

Answer is 8

Step-by-step explanation:

Marks scored=20

Correct answer=12

Incorrect answers=20-12=8

Answer 2

Answer:

48

Step-by-step explanation:

Given, marks = 20 & correct answers = 12

=> for 12 correct answer marks = 20

therefore for 1 correct answer mark = 20 / 12

If the total marks = 100, then the number of questions = 60 (ie 12 * 5)

so the number of incorrect answer if the total marks is 100 = 60 - 12 = 48
