Directions: In this question, relationship between different elements is shown in the statements. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. The statement is followed by some conclusions. Study the conclusions based on the given statement and select the appropriate answer.
Statements:& W < U = V ≤ X,& & V > Y ≥ Z,& & Y < P ≤ Q = RConclusions:& I. W > Z,& & II. Z < R
Options
- AOnly conclusion I follows
- BOnly conclusion II follows
- CEither conclusion I or conclusion II follows.
- DBoth the conclusion follow
Correct answer
B. Only conclusion II follows
Step-by-step solution
Only conclusion II follows
Option B, 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
Hence, option B is correct.
Hence, option B is correct.
