Q: In a family, the ages of the siblings are as follows: X is older than Y but younger than Z. W is younger than X but older than V. Who is the oldest sibling? (2023)
Solution: The order of ages is Y < V < W < X < Z. Therefore, Z is the oldest sibling.
Steps: 5
Step 1: Identify the relationships between the siblings based on the information given.
Step 2: From the statement 'X is older than Y but younger than Z', we can write the order as Y < X < Z.
Step 3: From the statement 'W is younger than X but older than V', we can write the order as V < W < X.
Step 4: Now combine the two orders: V < W < X < Z.
Step 5: From the combined order, we can see that Z is the oldest sibling.
