Two Statements are given followed by two conclusions numbered I and II. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusion logically follow(s) from the statements.
Statements:
1. All bottles are black.
2. All black are white.
Conclusions:
(I) All blacks are bottles.
(II) Some blacks are not white.
Answer & explanation
Correct answer: option 3
The correct answer is Option 3:Neither conclusion follows
- Statement 1: All bottles are black.
- Statement 2: All black are white.
So, we can combine them as: All bottles are white (since bottles → black → white).
(I) All blacks are bottles → This is the reverse of Statement 1. From “All bottles are black,” we cannot say all black are bottles. So, this does not follow.
(II) Some blacks are not white → This contradicts Statement 2 (“All black are white”). So, this also does not follow.
Thus, neither conclusion follows.
