Introduction to Statement and Conclusions in RRB Exams
Welcome, future railway professionals! If you are gearing up for the highly competitive RRB NTPC and RRB Group D exams, you know that the General Intelligence and Reasoning section is a crucial scoring area. Among the various topics in this section, 'Statement and Conclusions' stands out as a test of your logical deduction and critical thinking skills. These questions might seem straightforward, but they are designed with subtle traps that can easily confuse aspirants. Mastering this topic can significantly boost your overall score and give you an edge over the competition.
A typical question presents you with one or more statements followed by a set of conclusions. Your task is to determine which of the given conclusions logically and definitively follows from the information provided in the statements, irrespective of commonly known facts. This guide is designed to be your one-stop resource for mastering Statement and Conclusions. We will break down the fundamental concepts, explore powerful rules and strategies, walk through solved examples, and provide you with practice questions to solidify your understanding. Let's begin your journey to conquering this important reasoning topic!
Understanding the Core Concepts: Statement vs. Conclusion
Before diving into the rules and tricks, it's essential to have a crystal-clear understanding of the two basic components of these questions.
What is a Statement?
In the context of RRB exams, a statement is a piece of information, a fact, an opinion, or an observation that is presented to you. For the purpose of answering the question, you must consider the given statement to be 100% true, even if it seems absurd or contradicts real-world knowledge. Your personal opinions, beliefs, and general knowledge have no place here. The statement is the entire universe of information from which you must draw your conclusions.
Example:
- Statement: All cats are dogs.
In reality, we know this is false. However, for solving the question, you must accept this as a universal truth.
What is a Conclusion?
A conclusion is a judgment or an inference that is derived logically from the given statement(s). A conclusion is considered valid or 'following' only if it is directly and unequivocally supported by the information presented in the statement. If a conclusion requires an assumption or additional information not present in the statement, it is not a valid conclusion.
Example:
- Statement: The quality of education in government schools has seen a significant decline in recent years.
- Possible Conclusion: The government needs to take immediate steps to improve the condition of its schools. (This is a logical inference based on the problem highlighted in the statement).
The Golden Rule: Stick to the Statement
This is the most critical rule in this topic. You must confine your thinking strictly to the information given in the statement. Do not add any information from your side. Your job is not to verify the statement's truthfulness but to assess the conclusion's logical validity based on that statement.
Key Rules and Strategies to Solve Statement and Conclusion Questions
To navigate these questions effectively, you need a set of reliable rules and strategies. Internalizing these will help you avoid common pitfalls and arrive at the correct answer quickly.
Rule 1: Avoid Assumptions and External Knowledge
As mentioned in the golden rule, never bring your own knowledge into the picture. A conclusion must be a direct consequence of the statement. If you have to make an assumption to connect the statement and the conclusion, the conclusion does not follow.
Example:
- Statement: To be successful in life, one must be honest and hardworking.
- Conclusion: All successful people are honest and hardworking.
Analysis: The statement provides a path to success ('one must be...'), but it does not claim that this is the *only* path. It's possible for people to be successful through other means. Therefore, concluding that 'all' successful people follow this path is an assumption and does not logically follow.
Rule 2: Identify Keywords and Qualifiers
Words like 'all', 'some', 'none', 'only', 'few', 'always', 'never', 'possibly', 'must' are extremely important. They define the scope of the statement and the conclusion. Pay close attention to them.
- All/Every/Always: Universal and definite. Leaves no room for exceptions.
- Some/Few/Many: Partial and not universal. Implies that at least one exists, but not all.
- None/Never: Universal negative. Completely excludes a possibility.
- Only: A restrictive word. 'Only A is B' means if it's B, it must be A.
- Possibly/Might/May: Indicates a possibility, not a certainty. A conclusion that uses 'possibly' cannot be a definite conclusion.
Rule 3: Look for Direct and Indirect Connections
A valid conclusion will always have a logical link to the statement. The connection can be direct (explicitly stated) or indirect (implied). However, an implied connection must still be a logical certainty, not a mere possibility.
Example:
- Statement: The use of non-conventional energy sources is increasing, as they are cheaper and less polluting.
- Conclusion: Conventional energy sources are more expensive and cause more pollution.
Analysis: The statement says non-conventional sources are 'cheaper' and 'less polluting'. This comparison implies that conventional sources are relatively 'more expensive' and 'more polluting'. This is a valid indirect connection.
Rule 4: Beware of Restatements
A conclusion is an inference, not a repetition. If a 'conclusion' simply rephrases the statement using different words without adding any new logical deduction, it is often considered invalid. The purpose is to deduce, not to paraphrase.
Rule 5: The 'Possibility' vs. 'Certainty' Test
A valid conclusion must be a certainty derived from the statement. If a conclusion is just a possibility, it does not follow. Ask yourself: 'Does this conclusion *have* to be true based on the statement?' If the answer is 'not necessarily' or 'maybe', then it's not a valid conclusion.
Rule 6: The Negative Conclusion Rule
Generally, a positive statement does not lead to a negative conclusion. Similarly, a negative statement won't usually lead to a positive conclusion. However, there are exceptions, especially when dealing with words like 'all' or 'only'.
Example:
- Statement: All boys in this class passed the exam.
- Conclusion: No boy in this class failed the exam.
Analysis: Here, the positive statement 'all passed' logically implies the negative conclusion 'none failed'. This is a valid deduction.
Rule 7: Handling Two or More Statements
When you have multiple statements, you must find a common term or link to connect them. The conclusion should be a logical synthesis of the information provided in all statements. If a conclusion is based on only one of the statements and ignores the other, it might be invalid.
Common Traps and How to Avoid Them
Examiners often set traps to test your attention to detail. Being aware of them can save you valuable marks.
Trap 1: The Far-Fetched Conclusion
This is a conclusion that goes too far beyond the scope of the statement. It makes a broad generalization that isn't supported by the limited information provided.
Example:
- Statement: Company X saw its profits increase by 20% this year after launching a new product.
- Trap Conclusion: The new product is a massive success across the country.
Analysis: Increased profits for the company don't necessarily mean the product is a success 'across the country'. The success could be localized or due to other factors. This conclusion is too broad.
Trap 2: The Real-World Bias
As repeatedly stressed, you might be given a statement that is factually incorrect. The trap is to let your real-world knowledge influence your judgment. Ignore reality and focus solely on the given text.
Trap 3: The Ambiguous Conclusion
Sometimes, a conclusion is worded vaguely. A valid conclusion should be clear and precise. If a conclusion is open to multiple interpretations, it is likely not a strong logical deduction.
Step-by-Step Approach to Solving Questions
Follow this systematic approach to tackle any Statement and Conclusion question with confidence:
- Read the Statement(s) Carefully: Understand the exact meaning, paying close attention to keywords and qualifiers.
- Accept the Statement as 100% True: Temporarily forget your own knowledge and accept the given information as fact.
- Analyze Each Conclusion Individually: Read the first conclusion and compare it against the statement(s).
- Check for Logical Linkage: Determine if the conclusion is a direct, logical, and certain deduction from the statement. Ask yourself: 'Does the statement force this conclusion to be true?'
- Apply the Rules: Use the rules mentioned above (avoid assumptions, check keywords, beware of traps) to validate the conclusion.
- Repeat for Other Conclusions: Follow the same process for the second conclusion and any subsequent ones.
- Choose the Correct Option: Based on your analysis, select the appropriate option (e.g., Only I follows, Only II follows, Both I and II follow, Neither I nor II follows).
Solved Examples with Detailed Explanations
Let's apply these concepts to some examples similar to those found in RRB exams.
Example 1
Statement: The Indian economy is heavily dependent on the monsoon. Good monsoons lead to a rise in agricultural output.
Conclusions:
- I. A good monsoon is beneficial for the Indian economy.
- II. All other sectors of the Indian economy are unaffected by the monsoon.
Explanation:
- Analyzing Conclusion I: The statement says the economy is 'heavily dependent' on the monsoon and a good monsoon 'leads to a rise in agricultural output'. Since agriculture is a major part of the economy, a rise in its output would benefit the economy. So, Conclusion I logically follows.
- Analyzing Conclusion II: The statement says the economy is 'heavily' dependent, which implies a strong dependence, but it doesn't say that *only* agriculture is affected or that *all other* sectors are unaffected. This is an extreme conclusion and an assumption. So, Conclusion II does not follow.
Answer: Only conclusion I follows.
Example 2
Statement: All players must reach the stadium by 8:00 AM. Sachin is a player. No player is allowed to bring their own food.
Conclusions:
- I. Sachin must reach the stadium by 8:00 AM.
- II. Sachin did not bring his own food.
Explanation:
- Analyzing Conclusion I: The statement says 'All players must reach by 8:00 AM' and 'Sachin is a player'. Combining these two, it is a direct deduction that Sachin must also reach by 8:00 AM. So, Conclusion I follows.
- Analyzing Conclusion II: The statement says 'No player is allowed to bring their own food'. This is a rule. However, we cannot be 100% certain that Sachin followed this rule. The statement lays out a requirement, not a factual account of what happened. It tells us what is allowed, not what Sachin actually did. Therefore, we cannot definitively conclude that he did not bring his food. So, Conclusion II does not follow.
Answer: Only conclusion I follows.
Example 3
Statement: The best evidence of India's glorious past is the growing popularity of Ayurvedic medicines in Western countries.
Conclusions:
- I. Ayurvedic medicines are not popular in India.
- II. Allopathic medicines are more popular in India.
Explanation:
- Analyzing Conclusion I: The statement talks about the popularity of Ayurvedic medicines in the West. It gives no information about their popularity (or lack thereof) in India. Concluding they are not popular in India is an assumption. So, Conclusion I does not follow.
- Analyzing Conclusion II: The statement doesn't mention allopathic medicines at all. Any conclusion about them would be completely outside the scope of the given information. So, Conclusion II does not follow.
Answer: Neither I nor II follows.

| 3 |
Statement: All hardworking students pass the exam. Some hardworking students are from rural areas.
Conclusions: I. Some students from rural areas pass the exam. II. No student from a rural area fails the exam. |
| 4 |
Statement: Quality has a price tag. India is allocating lots of funds to education.
Conclusions: I. The quality of education in India will improve soon. II. Funding alone can enhance the quality of education. |
| 5 |
Statement: Use of plastic is harmful to the environment. All paper is biodegradable and environmentally friendly.
Conclusions: I. We should ban plastic. II. We should use paper instead of plastic. |
Solutions and Explanations for Practice Questions
Solution 1:
Explanation: The statement is about the runs scored, not the composition of the team. We know spinners scored 80% of the runs (160/200), but we cannot conclude that 80% of the players are spinners. This is a common trap confusing contribution with composition. Conclusion I does not follow. The statement gives no information about who the opening batsmen were. Conclusion II does not follow.
Answer: Neither I nor II follows.
Solution 2:
Explanation: The statement says parents are 'prepared to pay any price'. This shows their strong desire and commitment to their children's education. Conclusion II is a direct inference from this sentiment. The statement does not imply that parents are 'well off'; it only states their willingness to pay, which might involve making sacrifices. Conclusion I is an over-generalization.
Answer: Only conclusion II follows.
Solution 3:
Explanation: We know: (A) All hardworking students pass. (B) Some hardworking students are from rural areas. Combining these, the 'some' hardworking students who are from rural areas must also pass the exam. Therefore, Conclusion I, 'Some students from rural areas pass the exam,' is a valid deduction. Conclusion II says 'No student from a rural area fails'. We only know about the hardworking ones. What about rural students who are not hardworking? The statement gives no information about them, so they could fail. Thus, we cannot make this universal negative conclusion.
Answer: Only conclusion I follows.
Solution 4:
Explanation: The statement links quality with a price (funds). Since India is allocating funds, it is logical to infer that the quality of education is expected to improve. Conclusion I is a valid inference. However, Conclusion II uses the word 'alone'. The statement implies funding is necessary for quality but does not say it's the *only* thing required. Other factors like good teachers, infrastructure, and policies are also important. Therefore, Conclusion II is too extreme and does not follow.
Answer: Only conclusion I follows.
Solution 5:
Explanation: The statements present facts: plastic is harmful, and paper is environmentally friendly. Conclusions I and II are courses of action or suggestions. While they seem logical in a real-world context, a conclusion must be a deduction of fact, not a suggested action. The statement doesn't say plastic *should be* banned or paper *should be* used. It only states their properties. Therefore, neither conclusion is a direct logical deduction from the given information.
Answer: Neither I nor II follows.
