Difficulty: Easy
Correct Answer: If both conclusions I and II follow
Explanation:
Introduction / Context:
This question checks transitivity in a chain of strict inequalities. When each comparison is strict (">"), we can pass the relation forward to deduce farther-apart elements. The task is to test two conclusions derived from L > M > N > P.
Given Data / Assumptions:
Concept / Approach:
Use transitivity of strict order. If a > b and b > c, then a > c. Chaining multiple strict inequalities preserves strictness end-to-end. No equalities or non-strict signs (≥, ≤) are present to weaken the conclusion.
Step-by-Step Solution:
From L > M and M > N, we obtain L > N (by transitivity).From L > N and N > P, we obtain L > P (I is true).Separately, from M > N and N > P, we obtain M > P (II is true).
Verification / Alternative check:
Create a numeric model that satisfies the premises: let L=7, M=5, N=3, P=1. Then L > P (7 > 1) and M > P (5 > 1) both hold, confirming the deductions.
Why Other Options Are Wrong:
Options a/b assert only one conclusion; d says “either”, and e says “neither”. Since both I and II are compelled by transitivity, these alternatives understate the certainty or contradict the logical result.
Common Pitfalls:
Mistaking strict chains for non-strict and concluding L ≥ P or M ≥ P instead of L > P and M > P. Another error is skipping a link (e.g., comparing L to P without explicitly chaining via M and N), which can obscure the role of transitivity.
Final Answer:
If both conclusions I and II follow
