Three statements are given, followed by two conclusions numbered I and II. 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 from the statements.
Statements:
1) All cobblers are masons.
2) No, a mason is an electrician.
3) Some electricians are plumbers.
Conclusions:
I. All plumbers can never be masons.
II. At least some electricians are cobblers.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3, i.e., Only Conclusion I follows.
Conclusions:
I. All plumbers can never be masons → Follows (In the statement, No, mason is an electrician, and some electricians are plumbers, so those parts that are in the electrician are not masons.)
II. At least some electricians are cobblers → Does not follow (All Cobblers are masons and no masons are electricians, so definitely no cobblers are electricians.)
