Question: X is older than Y, Z is younger than W and V is older than Y. Is Z younger than X?

I. W may not be older than V.

II. W is not older than V.


  1. If the question can be answered with the help of statement I alone,
  2. If the question can be answered with the help of statement II alone,
  3. If both, statement I and statement II are needed to answer the question, and
  4. If the statement cannot be answered even with the help of both the statements.

Correct Option:4

Taking only first statement into consideration:
Nothing absolute can be said about Z and X
Now taking only second statement into consideration:
$W \leq V$
As it is given that X is older than Y; Z is younger than W and V is as old as Y.
and through second statement we know that W is younger or as old as V.
So using above four information we can conclude that Z is not older than X.
Z is either younger or as old as X.
Hence answer will be B).
