Question

1. In a competitive exam, 3 marks are given for every correct answer and 1 mark is
deducted for every incorrect answer. Raju copied some answers from Reema and
answered all the questions. He scored 20 marks though he got 10 correct answers.
How many incorrect answers had he attempted? What values are promoted in the question?​

Answer 1

Answer:

Step-by-step explanation:

let x be the no. of correct answers and y be the no. of wrong answers.

total marks =20

therefore 3x-y= total marks

                 3x10-y=20

                 30-y =20

                     -y=20-30

                     -y= -10

                      y= 10

Answer 2

Answer:

10 incorrect answer

Step-by-step explanation:

Marks Given For correct answer= 3

Marks Given For incorrect answer = (-1)

Raju scored = 20 marks

Raju's marks for correct answer= 10*3=30

Raju's marks for incorrect answer= (-1)*x = -1x

Answers he attempted incorrectly= 30+(-1x)

20=30+(-1x)

20-30=(-1x)

-10=(-1x)

-10/-1=x

10= x

So, he attempted 10 incorrect answers.

VALUE=We should not use unfair means because by doing so we violate the value of honesty in our character. The values promoted independent work,not copying.
