In the question one statement is given, followed by two conclusions, I and II. You have to consider the statements to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements. Statement : 55% of Manisha's office colleagues went to watch the movie. Conclusion I : Manisha went to watch the movie. Conclusion II : Manisha did not go to watch the movie.
Either I or II follows
Understanding Statement and Conclusion Reasoning
This question asks us to analyze a given statement and determine which of the provided conclusions logically follows from it. In these types of questions, we must strictly adhere to the information given in the statement, treating it as absolutely true, even if it contradicts common knowledge.
Analyzing the Statement
The statement is:
Statement: 55% of Manisha's office colleagues went to watch the movie.
This statement provides specific information about a subset of Manisha's office colleagues. It tells us that a certain percentage (55%) of people who work in the same office as Manisha went to see the movie.
What the statement does not tell us is whether Manisha herself was part of the 55% who went or part of the remaining 45% (or others, if any) who did not go. The statement is solely about her colleagues.
Analyzing the Conclusions
We have two conclusions:
- Conclusion I: Manisha went to watch the movie.
- Conclusion II: Manisha did not go to watch the movie.
Based on the statement alone, can we conclude that Manisha went to watch the movie? No. The statement gives no information about Manisha's actions, only about her colleagues.
Based on the statement alone, can we conclude that Manisha did not go to watch the movie? No. Again, the statement is silent on Manisha's attendance.
Determining Which Conclusion Follows
Since the statement provides no direct information about Manisha's movie attendance, neither Conclusion I nor Conclusion II can be definitively deduced as true based solely on the statement.
However, let's look at the nature of the two conclusions. Conclusion I states that Manisha went, and Conclusion II states that Manisha did not go. These two possibilities cover all potential scenarios regarding Manisha's movie attendance. Manisha must either have gone to the movie or she must not have gone. These are mutually exclusive and exhaustive possibilities for Manisha's action.
In reasoning questions with "Either/Or" options, if the given statement doesn't allow us to definitively conclude one specific outcome, but the conclusions represent two opposing possibilities that together cover all cases, then the "Either I or II follows" option is often correct. This is because while we don't know which one is true from the statement, one of them necessarily must be true in reality.
Therefore, although the statement doesn't inform us about Manisha, the conclusions present the only two possibilities for her. Thus, either Conclusion I follows or Conclusion II follows.
Conclusion Analysis Summary
| Statement | 55% of Manisha's office colleagues went to watch the movie. |
|---|---|
| Information about Manisha | None provided directly regarding her movie attendance. |
| Conclusion I (Manisha went) | Cannot be concluded from the statement. |
| Conclusion II (Manisha did not go) | Cannot be concluded from the statement. |
| Relationship between I and II | Mutually exclusive and exhaustive possibilities for Manisha's action. |
| Overall Result | Either I or II must be true, even if the statement doesn't tell us which one. |
Revision Table: Statement and Conclusion Basics
| Concept | Explanation | Key Principle |
|---|---|---|
| Statement | The given fact(s) that must be assumed true. | Assume truth, ignore outside knowledge. |
| Conclusion | Inference(s) drawn from the statement. | Must logically follow from the statement ONLY. |
| "Follows" | Means "can be logically deduced" from the statement. | No external information or assumptions allowed. |
| Either/Or Conclusions | When two conclusions represent opposing, exhaustive possibilities. | Often correct if the statement doesn't specify which is true, but one must be. |
Additional Information: Types of Deductive Reasoning
Statement and Conclusion questions fall under deductive reasoning. Deductive reasoning starts with a general statement or premise and works towards a specific conclusion. If the original statements are true, then the conclusion drawn through deductive reasoning must also be true.
However, in this specific question structure involving "Either/Or" conclusions covering all possibilities, the logic applied is slightly different. It tests the understanding that even without direct information in the statement, two contradictory and exhaustive conclusions about a subject mean that one of them must be true in reality, leading to an "either/or" scenario being the valid outcome derived from the possibilities presented.
It is crucial in these problems to distinguish between what the statement *implies* and what it *explicitly states*. This statement explicitly states something about colleagues but implies nothing about Manisha herself.
Important Questions from Statements and Conclusions
In the following question below are given some statements followed by some conclusions based on those statements. Taking the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusion logically follows the given statements.
Statements:
I. All A are B.
II. Some B are C.
Conclusions:
I. Some A are C.
II. Some A are not C.
III. Some A are B.
Directions: The questions has a statement followed by two conclusions I and II. You have to decide which of the conclusions follows from the given statement and mark your answer as
