Write the inequality chain directly as you read: W > Z > Y > X > V. Once ordered, the person at the second position from the top is the second oldest.
Establish First Sequence
Z is older than Y but younger than W. This gives the sequence: W > Z > Y.
Establish Second Sequence
X is older than V but younger than Y. This gives the sequence: Y > X > V.
Combine Sequences
Merging (W > Z > Y) and (Y > X > V) results in the final age ranking: W > Z > Y > X > V.
Identify Second Oldest
Looking at the chain W > Z > Y > X > V, the oldest is W and the second oldest is Z.
A: X is the fourth oldest, C: V is the youngest (fifth), B: W is the oldest (first).
D is correct because combining the given conditions results in the age order W > Z > Y > X > V, making Z the second oldest.
In ranking questions, always verify if the question asks for the second oldest or second youngest, as candidates often overlook this detail under exam pressure.
