Only conclusion II follows

Option 2, is hence the correct answer.

Common explanation:

There is a priority order of the symbols according to which the priority of the symbol is decided to reach the conclusion. Whenever there are two or more type of symbols are there between two objects whose relation is to be determine we have to use this order.

If the direction of sign is opposite between that two objects, no relation can be stated perfectly and we have to say that it does not follow.

Priority Order:

1.      > and < 

2.      ≥ and  ≤

3.           =

For conclusion I: W > Z
Combining statement I and II:

W < U = V > Y ≥ Z

As, the sign between W and Z are in opposite direction so, the chain breaks, hence we cannot conclude the relation between W and Z.

Hence, the conclusion does not follow.

For conclusion II: Z < R

Combining statement II and III:

Z ≤ Y < P ≤ Q = R

As, “<” sign is the highest prior sign here, so, Z < R is the actual relation.

Hence, the conclusion follows.
Only conclusion II follows
