Question
Which of the following symbols should replace the
question marks (?) in the given expression in order to make the expression ‘N ≤ Q’ definitely true? R > Q ≥ M, P > N (?) O ≤ MSolution
P > N < O ≤ M ≤ Q < R                    Q > N. Hence option 1 is incorrect. P > N ≤ O ≤ M ≤ Q < R                    N ≤ Q. Hence option 2 is correct. P > N > O ≤ M ≤ Q < R                    No relation can be established between Q and N. Hence option 3 is incorrect. P > N ≥ O ≤ M ≤ Q < R                    No relation can be established between Q and N. Hence option 4 is incorrect.
