Which of the following symbols should replace (1) and (2), respectively in the given expression in order to make the expression X < H definitely true?

Z ≤ W ≤ X = V (1) U ≤ N ≤ T; O > N (2) K = H

Solution

Given expression: Z ≤ W ≤ X = V (1) U ≤ N ≤ T; O > N (2) K = H On combining, Z ≤ W ≤ X = V (1) U ≤ N (2) K = H 1) Z ≤ W ≤ X = V ≤ U ≤ N ≤ K = H              X ≤ H. Hence option 1 is not correct. 2) Z ≤ W ≤ X = V ≤ U ≤ N > K = H              No relationship can be established between X and H. Hence option 2 is not correct. 3) Z ≤ W ≤ X = V ≤ U ≤ N < K = H              H > X. Hence option 3 is not correct. 4) Z ≤ W ≤ X = V = U ≤ N ≤ K = H              X ≤ H. Hence option 4 is not correct.
