Logical Reasoning - Statement and Conclusion - Discussion

The statement doesn't say anything about satisfaction. So, anyone please explain me the right answer.

D is the correct answer.

According to the given statement,

Hardwork is necessary to pass the exam but it is not mentioned if only hardwork is sufficient there are other parameter as well apart from hardwork to pass the exam.

But if someone does not work hard, he will surely not pass the exam.

X implies Y. Then Not Y implies Not X. But Not X does not imply not Y. D is absolutely wrong.

Since X implies Y is a rule, for one, it must be applicable to a group of these "one"s, thus leading to the conclusion that B must be true.

I agree @Aman, definitive words like all, always, at least, only, exactly should not come in conclusion. Option D is the right one.

D is the correct option. I agree with the given answer.

I don't think option D is correct. One does not always have to work hard to pass in exams. There are other factors as well.

For example, one can be simply attentive in class and knows what the subject is about and he can pass the exams, being attentive in class is not really a lot of hard work. Secondly, there is always the luck of the person.

If there is an MCQ exam, a person might just select random options and might be lucky enough to pass. A is the closest option of all.

D can't not be true because it cannot be said vice verse. It is yes if you want to pass exam you will have to work hard but it is no guarantee that if you work hard you are going to make it.

D says "All". Definitely not true.

Though I can say that "A" is more close because hard work is required to pass yet not necessary that he will make in-spite of working hard so both are related 'pass the exam' related to 'hard work'.

Some times smart work will also make the people success.

The statement means that if you work hard you can be certain to pass but it does not imply that without hard work you won't pass hence option B.

D is correct.

A is incorrect because exam is not related to hard work but "pass" exam is related to hard work. The exam itself has no relation.

B is incorrect because of "all" which is misunderstood. The statement does not reference anything to "all" will pass just because they work hard. It is more of a possibility to pass if you work hard. Using "all" is irrelevant.

C & E is incorrect because one statement either mentions anxiety while the other satisfied person, which in no one has anything to do with the statement above.

What follows, D is left and logically is the best choice.
