Directions: In each question below there are given some statements followed by some conclusions. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows/follow from the given statements, disregarding commonly known facts.
Statements:
Some crops are drops.
All drops are pearls.
No crops are wishes.&
Conclusions:&
I. No wish is a drop.
II. All drops being wish is a possibility.
Options
- ANeither I nor II follows
- BOnly I follows
- CEither II or III follows
- DOnly I and III follow
Correct answer
A. Neither I nor II follows
Step-by-step solution
Venn Diagram Method:
Analytical Method:
In the both the conclusions, the we need to derive a relationship between the classes ‘wish’ and ‘drop’ which are present in S3 and S1 respectively.
Here, the middle term ‘crop’ is distributed once in S3 and hence we can apply the deduction method and get the conclusion as ‘Some drops are not wishes’.
Clearly, neither of the two conclusions follows.
Option A is hence the correct answer.
