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 trees are fish.
All fishes are goats.
No goat is a flower.
Conclusions:
I. Some trees are goats.
II. Some fishes are not flowers.
III. Some flowers are not goats.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. All conclusions follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some trees are goats → True (As some trees are fish, and all fishes are goats, so, some trees are goats is also true.)
II. Some fishes are not flowers → True (As all fishes are goats, and no goat is a flower, so some fishes are not flowers is also true.)
III. Some flowers are not goats → True (As no goat is a flower, so, some flowers are not goats is also true.)
Hence, All conclusions follow.
