Three statements are given, followed by three conclusions numbered I, II, and III. 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 strawberries are bananas.
All bananas are avocados.
Some avocados are grapes.
Conclusion:
I. Some avocados are bananas.
II. Some grapes are bananas.
III. Some avocados are strawberries.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Only conclusions I and III follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some avocados are bananas → True (As all bananas are avocados, so, some avocados are bananas is also true.)
II. Some grapes are bananas → False (It is possible but no definite conclusion can be drawn.)
III. Some avocados are strawberries → True (As some strawberries are bananas, and all bananas are avocados, so, some avocados are strawberries is also true.)
