In a class test containing 10 questions, 2 marks are rewarded for every correct answers and
1 mark is deducted for every incorrect answer and 0 for each question not attempted.
i) Ravi gets 4 correct answers and 6 incorrect answers.
ii) Reenu gets 5 correct and 5 incorrect answers.
Whose performance is better?
​

Answer 1

Answer:

i) No. of correct answers Ravi gets = 4

Marks of correct answers Ravi gets = ( 2*4)

                                                           = 8 marks

No. of wrong answers Ravi gets = 6

Marks of wrong answers Ravi gets = ( 6*1)

                                                          = 6 marks

Total marks = ( 8-6 )

                    = 2 marks

ii) No. of correct answers Reenu gets= 5

Marks of correct answers Reenu gets =  ( 5*2 )

                                                               = 10 marks

No. of incorrect answers Reenu gets = 5

Marks of incorrect answers Reenu gets = ( 5*1 )

                                                                  = 5 marks

Hence , Reenu' s performance is better.
