Directions (80-82):In each of the following questions assuming the given statements to be true, find which of the two conclusions I and II given below is/are definitely true and give your answer accordingly.

Statement: A < G < R > J ≤ Q = Z ≤ O; P > T = I ≤ J ≥ M
Conclusion: I. O ≥ I
II. M ≥ T
III. P > M

The correct answer is Only I is true.

To determine which conclusion(s) are definitely true, let us break down and combine the given statements step-by-step.

Given Statements:
1. $A<G<R>J\le Q=Z\le O$
2. $P>T=I\le J\ge M$

Now, let us evaluate each conclusion independently:

Evaluating Conclusion I: $O\ge I$

From statement 1, we can establish the relationship between $O$ and $J$:
$O\ge Z=Q\ge J\Rightarrow O\ge J$

From statement 2, the relationship between $J$ and $I$ is given as:
$J\ge I$

Combining these two results:
$O\ge J\ge I\Rightarrow O\ge I$

Hence, Conclusion I is definitely true.

Evaluating Conclusion II: $M\ge T$

From statement 2, we have the chain connecting $T$ and $M$:
$T=I\le J\ge M$

Since the inequality signs between $T$ and $M$ are facing opposite directions ($\le$ and $\ge$), no definite relationship can be determined between $M$ and $T$.

Hence, Conclusion II is not definitely true.

Evaluating Conclusion III: $P>M$

From statement 2, we have:
$P>T=I\le J\ge M$

Again, due to conflicting inequality signs along the path from $P$ to $M$, no clear relation exists between $P$ and $M$.

Hence, Conclusion III is not definitely true.

Therefore, only Conclusion I is true.
