Question

in an objective test contains 25 questions. a student is to be answered +5marks for every correct answer. -5 for every incorrect answer and zero for not writing answer. create the ways of scoring 12 marks by a student

Answer 1

+5 is given for every correct answer,

-5 is given for every incorrect answer,

and 0 for no attempt.

So, if you write an equation for total marks we have:

Total = 5 (correct) -5 (incorrect) + 0 (unattempted)

Total = 5 [ correct - incorrect]

So, we can never get 12 as our total marks, because we have 5 as a multiple outside.
