Logical Reasoning - Statement and Conclusion
- Option : D
- Explanation : The opposites of ‘passed’ and ‘girls’ are not ‘failed’ and ‘boys’. Failed and boys are not mentioned in the statements. So, no conclusion is valid.
- Option : D
- Explanation : The logical form of ‘Most of Indian states existed before independence’ is ‘Some Indian states existed before independence’. It is same as conclusion I. Statement and conclusion cannot be the same. Conclusion II is also not implied. So, (d) is the answer.
- Option : A
- Explanation : After converting statement I, we can say that ‘a’ is true. ‘On time’ does not mean ‘not late’ in case of propositions. Thus, options (c) and (d) also not converse of (a).
- Option : D
- Explanation : The contextual meaning and logical meanings are different for both the terms. So, option (d) is the answer.
- Option : B
- Explanation : ‘Most teachers are hardworking’ is ‘Some teachers are hardworking’ in its logical form. Both statement and conclusion cannot be the same. So conclusion I is not implied. However, conclusion II ‘Some teachers are not hardworking’ is complimentary of I, so only II is implied. Thus, option (b) is the answer.
