These questions can be solved easily by tabular chart.


We will start reading each conditions and a 'correct' sign or 'wrong' sign accordingly.

From the condition (i) we get following tables.


Further applying condition (ii) we get following tables.


Applying condition (iii) we get following tables.


Further applying Condition (iv) we get following tables.


Further applying condition (v) we get following tables.


Further applying (vi) we get following tables.


Now we will mark 'Correct' on the only left space and mark 'wrong' on the remaining space. Then the following table emerges


With the help of the above tables we can solve all the questions easily.

Note: After drawing table further modification can be done according to given conditions. There is no need to draw further tables. Tables drawn further is just to explain the steps in elaborate manner.
