In a group of friends, X is older than Y but younger than Z. W is older than X. If Y is the youngest, who is the oldest? (2021)

Step 1: Identify the relationships between the friends based on their ages.
Step 2: We know that X is older than Y, which means Y is younger than X.
Step 3: We also know that X is younger than Z, which means Z is older than X.
Step 4: Since W is older than X, W is also older than Y because X is older than Y.
Step 5: Since Y is the youngest, and we have established that Z is older than X, Z must be older than Y as well.
Step 6: Therefore, since Z is older than both X and Y, Z is the oldest.
