NIMCET 2007 — Reasoning PYQ

1. Understanding the Problem Strategy

To find out which book occupies the lowest place, we need to analyze the comparative height/position clues given in the problem statement. We can represent "above" using the greater-than sign (>) or by arranging them vertically from top to bottom.

2. Breaking Down the Clues

Let's convert each statement into a logical inequality where a higher position is on the left (>) and a lower position is on the right (<):

• Clue 1: " $R$ is above $S$ "

  R > S

• Clue 2: " $P$ is below $S$ " (or $S$ is above $P$)

  S > P

• Clue 3: " $Q$ is below $P$ " (or $P$ is above $Q$)

  P > Q

• Clue 4: " $Q$ is below $T$ "

  T > Q

3. Combining the Arrangements

Now, let's combine Clue 1, Clue 2, and Clue 3 into a single continuous chain:

R > S > P > Q

From this chain, we can clearly see the relative vertical order of these four books from top to bottom:

1. Top: $R$

2. Second: $S$

3. Third: $P$

4. Fourth: $Q$

Now, let's consider the remaining book, $T$. Clue 4 states that T > Q ($Q$ is below $T$). Regardless of whether $T$ sits at the very top, between $R$ and $S$, or between $P$ and $Q$, it is explicitly stated to be above $Q$.

Since all books ($R$, $S$, $P$, and $T$) are positioned above $Q$, book $Q$ must be at the absolute bottom of the stack.

Final Answer

The book that occupies the lowest place is $Q$.

Therefore, the correct option is (b).
