Which of the following symbols should replace the sign

Solution

C ≥ D > M > S = Y > J ≥ K= Z                           Y ≥ Z is false and D > K is true. Hence option 1 is incorrect. C ≥ D > M > S = Y < J ≥ K= Z                           Y ≥ Z is false and D > K is also false. Hence option 2 is incorrect. C ≥ D > M > S = Y ≤ J ≥ K= Z                           Y ≥ Z is false and D > K is also false. Hence option 3 is incorrect. C ≥ D > M > S = Y ≥ J ≥ K= Z                           Y ≥ Z is true and D > K is also true. Hence option 4 is correct.
