In a group of five buildings named Pearl Towers, Sky Towers, Unity Towers, Cyber Towers and Indus Towers, Pearl Towers is taller than Sky Towers but shorter than Unity Towers. Unity Towers and Cyber Towers are of the same height, and Pearl Towers is also shorter than Indus Towers. Among all these buildings, which one is the second shortest in height?

Introduction / Context:
This verbal reasoning question tests your ability to compare and order items by height using a set of relational statements. Such ranking and ordering problems are very common in competitive exams and help to check whether you can convert English sentences into a clear logical order.

Given Data / Assumptions:

• Buildings: Pearl Towers (P), Sky Towers (S), Unity Towers (U), Cyber Towers (C), Indus Towers (I).
• P is taller than S.
• P is shorter than U.
• U and C are of the same height.
• P is shorter than I.
• No two different buildings, except Unity and Cyber, are of the same height.

Concept / Approach:
We will use inequality type relations (taller/shorter) to place each building in increasing order of height. Once we know the smallest (shortest) building, we can easily identify the second shortest by looking at the next item in the ordered list.

Step-by-Step Solution:
Step 1: From “Pearl Towers is taller than Sky Towers”, we write S < P in terms of height. Step 2: From “Pearl Towers is shorter than Unity Towers”, we get P < U. Step 3: From “Unity Towers and Cyber Towers are of same height”, we note U = C. Step 4: From “Pearl Towers is shorter than Indus Towers”, we get P < I. Step 5: Combine all relations around Pearl Towers: S < P < U, S < P < C, and S < P < I. Step 6: Clearly, Sky Towers is shorter than Pearl Towers, and no other building is given as shorter than Sky Towers. So, Sky Towers is the shortest. Step 7: Buildings Unity, Cyber and Indus are all taller than Pearl Towers, so they must stand above Pearl Towers in the height order. Step 8: Therefore, after the shortest (Sky Towers), the next taller building must be Pearl Towers, independent of the exact order among Unity, Cyber and Indus.
Verification / Alternative check:
Even if Indus Towers is the tallest or Unity and Cyber are placed anywhere above Pearl Towers, the only strict information about the lower end is that S is below P and all others are above P. So the relative positions of U, C and I do not affect which building is the second shortest.

Why Other Options Are Wrong:
Sky Towers: It is the shortest, not the second shortest, because it is explicitly shorter than Pearl Towers and no building is said to be shorter than Sky Towers. Indus Towers: It is taller than Pearl Towers, so it cannot be second from the bottom. Unity Towers: Unity is taller than Pearl Towers, so it must be above Pearl Towers in the order. Cyber Towers: Cyber Towers has the same height as Unity Towers, which is taller than Pearl Towers, so it is not among the two shortest buildings.
Common Pitfalls:
Many learners overthink the exact order between Unity, Cyber and Indus even though it is not required. The question only asks for the second shortest, so you only need to focus on the lower end of the order, not the whole ranking. Another common mistake is to think that if we do not know the entire order uniquely, we cannot answer the question, which is not true here.

Final Answer:
Thus, the second shortest building in the group is Pearl Towers.
