In each of the question below are given four statements followed by three conclusions numbered I, II and III. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from three given statements disregarding commonly known facts.
Statements:Some nails are plates.
Some plates are disks.
All disks are mirrors.
All mirrors are tyres.
Conclusions:I.Some tyres are plates.
II.Some tyres are nails.
III.Some mirrors are plates.
The Venn Diagram for the given syllogism is as shown below:
Based on the diagram, atleast some tyres are plates and at least some mirrors are plates. Hence, conclusions I and III are implied. There is no way to confirm that some plates are nails. So, the correct option is option (b).
