Statements:  M ! N, N ^ O, O # N, N @ P Conclusions:       I. M @ N     II. N ^ M       
III. O ! P                  
IV. S % N

Decoded Statement: M ≤ N, N ≥ O, O < N, N > P  Decoded conclusion:  I. M > N                    II. N ≥ M                               III. O ≤ P                               IV. S = N M ≤ N ≥ O < S > P                             M ≤ N. Hence conclusion I is not true. M ≤ N ≥ O < S > P                              M ≤ N. Hence conclusion II is true. M ≤ N ≥ O < S > P                             No relationship can be established between O and P. Hence conclusion III is not true. M ≤ N ≥ O < S > P             No relationship can be established between S and N. Hence conclusion IV is not true.
