When you mark the correct option you get the marks or points
If you mark wrong option, you lose marks or points (usually in a 4 option question it is 1/3 or 1/4)
However, if you do not mark any option, you neither gain nor lose.
Hint: suppose you do not know any answer, your probability of gaining is 1/4 and probability of losing is 3/4. If you multiply with gains in each case, Your expectation is 1/4 *1 = 1/4 and expectation of losing is 3/4 * 1/3 = 1/4 again. So, equal probability of gaining and losing. ---> no gain in making guess work.
If you know for sure that 2 options of 4 are definitely wrong, and you make a guess,
probability of gaining = 1/2 * 1 = 1/2 and probability of losing = 1/2 * 1/3 = 1/6 -----> it is worth making a guess.

Simple. In a question in such an exam, you may have 4 options and have to choose any one of these; now these are possibilities:
[1] You choose an option and its correct - you get the mark
[2] You choose an option and its incorrect - you lost negative marks(say 1/4th mark)
[3] You do not mark any option and skip - No deduction of marks.
Negative marking means that you may be penalised for choosing the wrong option in an objective question.

In objective questions there are options. So anybody can choose any answer and if they aye lucky.. get marks.
In negative marking,if u choose a wrong answer you get minus marks. if u dont attempt the question, no deduction of marks.

if your answer is wrong when you are answering,instead of zero marks, negative marks will be given. that means the marks will be deducted from your overall marks you got for rightly answer es questions.
when you are in doubt, better leave the question.
