Three statements are given, followed by three conclusions numbered I, ll and IIl. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
Some engineers are doctors.
Some doctors are architects.
Some architects are designers.
Conclusions:
I. Some designers are engineers.
II. Some architects are doctors.
III. Some doctors are engineers.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Only conclusions II and III follow.
The least possible venn diagram is:
Conclusions:
I. Some designers are engineers. → Does not follow (As there is no direct relation between them)
II. Some architects are doctors. → Follows (As some doctors are architects. So, some architects are also doctors.)
III. Some doctors are engineers. → Follows (As some engineers are doctors. So, some doctors are also engineers.)
