Step-by-step Solution:

Quick Solution

The best way to solve this is to combine the comparison clues into a single ranking of the five people from tallest to shortest. Let's use the `>` symbol to mean "is taller than".

1. Combine the Initial Clues

• From clue 4 ("Eenu is taller than Anu") and clue 1 ("Anu is taller than Cini"), we get the chain: Eenu > Anu > Cini.
• From clue 2 ("Eenu is shorter than Binu"), we can add Binu to the front of this chain: Binu > Eenu > Anu > Cini.
• We also know from clue 3 that "Anu is shorter than Dany" (Dany > Anu), but we don't yet know where Dany fits relative to Binu and Eenu.

2. Use the Key Clue

The most important clue is the last one: "Binu is shorter than only one person."

• There are five people in total. If Binu is shorter than only one of them, it means Binu must be the second tallest person in the group.

3. Determine the Final Order

- We have the established order: Binu > Eenu > Anu > Cini.
- We know Binu is the second tallest, so there must be exactly one person who is taller than him.
- The only person left to place in the ranking is Dany.
- Therefore, Dany must be the one person who is taller than Binu.

The complete ranking from tallest to shortest is:

Dany > Binu > Eenu > Anu > Cini

Final Answer: The tallest person is Dany.
