It is given that, 
K @ Y > X; R = Y # T ≤ P < M. 
If we replace @ with ≥ and # with =, then we get
K ≥ Y > X; R = Y = T ≤ P < M. Then P > K is false and M > Y is true. 
If we replace @ with ≤ and # with >, then we get
K ≤ Y > X; R = Y > T ≤ P < M. Then P > K is false and M > Y is false. 
If we replace @ with ≤ and # with =, then we get
K ≤ Y > X; R = Y = T ≤ P < M. Then P > K is false and M > Y is true. 
If we replace @ with ≤ and # with <, then we get
K ≤ Y > X; R = Y < T ≤ P < M. Then P > K is true and M > Y is true. 
If we replace @ with < and # with >, then we get
K < Y > X; R = Y > T ≤ P < M. Then P > K is false and M > Y is false.
