In these questions, relationships between elements are shown using comparison symbols. Based on the given statements, you must decide which conclusions logically follow. Statement: A = M > P, N > R, A > T. Conclusions: I. T = P II. R < A

Difficulty: Medium

Correct Answer: If neither conclusion I nor conclusion II follows.

Explanation:


Introduction / Context:
This problem is from the inequalities and logical deductions area of reasoning. Symbols such as "=", ">", and "<" indicate comparative relationships between elements. Your task is to determine which of the given conclusions must be true based solely on the information in the statement, without making extra assumptions.



Given Data / Assumptions:

  • A = M > P.
  • N > R.
  • A > T.
  • Symbols have their usual meanings: "=" means equal to, ">" means greater than.
  • Conclusions:
  • I. T = P.
  • II. R < A.


Concept / Approach:
We convert the combined statement into a clear chain of inequalities. Then we see what definite relationships are established and whether they justify each conclusion. A conclusion "must follow" only if it is true in every possible arrangement that satisfies the statement. If there is any possible case where it fails, that conclusion does not follow.



Step-by-Step Solution:
Step 1: Simplify the given statement. From "A = M > P", we know A and M are equal, and they are both greater than P. So we can write A = M and A > P. We also have "A > T", so A is greater than T. We have "N > R", but there is no direct relation between N and A, or N and M in the statement. Step 2: Analyse Conclusion I: T = P. We know A > P and A > T, so both P and T are less than A. However, being less than A does not automatically mean they are equal to each other. It is possible that P < T or T < P or T = P. Because more than one arrangement is possible, T = P is not guaranteed. Therefore, Conclusion I does not necessarily follow. Step 3: Analyse Conclusion II: R < A. We know N > R, but we have no information about how N compares with A. R could be less than A, equal to A, or greater than A, depending on the unspecified relationship between N and A. So we cannot conclude R < A for sure. Therefore, Conclusion II also does not necessarily follow.


Verification / Alternative check:
Try constructing different numerical examples that satisfy the statement and see what happens to T and P, and R and A. For some valid assignments, T and P may be equal; for others, they are not. Similarly, R may or may not be less than A depending on the chosen values for N and A. This confirms that neither conclusion is guaranteed.



Why Other Options Are Wrong:
Options A and B claim that one of the conclusions follows, which is incorrect. Option C says that either I or II follows, but in reality neither is logically forced. Only the option stating that neither conclusion follows matches our analysis.



Common Pitfalls:
A common mistake is to assume transitivity where no link exists, such as guessing that because N > R and A > P, A must also relate to R in a specific way. Without explicit links, such assumptions are invalid in inequality reasoning.



Final Answer:
Hence, neither conclusion I nor conclusion II necessarily follows, so the correct choice is option D as stated.
