Question

Among six persons, P, Q, R, S, T and U, each one has a different weight. The weight of Q is more than only two other persons. The weight of P is more than U's weight. The weight of S is more than Q's weight. The weight of R is less than the weight of T. The weight of Q is more than the weight of T. U has the second highest weight among all the six persons. Who has the third highest weight among all six persons?

• A. S
• B. R
• C. P
• D. T

Answer 1

Answer:

A. S

The person who has the third highest weight among all six persons is S.

Let's organize the positions from 1st (heaviest) to 6th (lightest):
\text{1st (Heaviest)} > \text{2nd} > \text{3rd} > \text{4th} > \text{5th} > \text{6th (Lightest)}

1. Position of Q: The weight of $Q$ is more than only two other persons. This means there are exactly two people lighter than $Q$ (occupying the 5th and 6th spots), which places $Q$ in the 4th position.
   \text{\_} > \text{\_} > \text{\_} > \mathbf{Q} > \text{\_} > \text{\_}

2. Position of U and P: $U$ has the second highest weight among all six persons (2nd position). We are also told $P$'s weight is more than $U$'s (P > U), which naturally forces $P$ into the 1st position.
   \mathbf{P} > \mathbf{U} > \text{\_} > \mathbf{Q} > \text{\_} > \text{\_}

3. Positions of T and R: The clues state that Q > T and T > R (since $R$ is less than $T$). This leaves the remaining two lighter spots (5th and 6th) for $T$ and $R$ respectively.
   \mathbf{P} > \mathbf{U} > \text{\_} > \mathbf{Q} > \mathbf{T} > \mathbf{R}

4. Position of S: The final empty slot (3rd position) goes to $S$. This perfectly satisfies the condition that $S$'s weight is more than $Q$'s (S > Q).

Final Arrangement

\mathbf{P} > \mathbf{U} > \mathbf{S} > \mathbf{Q} > \mathbf{T} > \mathbf{R}

Looking at the ranking, S occupies the third position.
