Statement - Conclusions Questions and Answers

Answer: C

Correct answer: Some dresses in that shop are expensive.

If most of the dresses are expensive then certainly some are, so that conclusion follows with no further assumption. The others do not: “most” leaves the rest unaccounted for, and dresses that are not expensive need not be cheap - they may be moderately priced - still less can anything be said about the handloom ones.

Answer: C

Correct answer: Seventh floors have lifts.

A building with a seventh floor has more than three floors, so by the rule given it must have a lift. The others fail: buildings of two or three floors have no lift, so not all floors can be reached by one, and nothing says lifts serve only the upper floors.

Answer: C

Correct answer: No library is without books.

“Every library has books” and “no library is without books” say the same thing in different words, so that conclusion follows exactly. The others reverse the statement - claiming books are found only in libraries - or add what is not given about readers.

Answer: D

Correct answer: One-eighth of the boys play neither cricket nor football.

Half the boys play cricket, and a quarter of those - that is \( \tfrac{1}{4} \times \tfrac{1}{2} = \tfrac{1}{8} \) of all the boys - do not play football. So the boys who play at least one game number \[ \tfrac{3}{4} + \tfrac{1}{8} = \tfrac{7}{8} \] and the remaining \( \tfrac{1}{8} \) play neither.

Answer: D

Correct answer: In case of emergency, he may forget his address and may need the card to contact his house.

The card is to be carried against the possibility of a serious accident, and the details it must bear - address and telephone number - are exactly what would be needed to reach a man’s home when he cannot supply them himself. The others go beyond the statement: nothing is said about transfusion procedure, about the police, or about what anyone is supposed to remember.

Answer: D

Correct answer: None of these

The four percentages are separate counts over the same workforce, and nothing links one to another. Sincere and insincere employees may be of either sex; the Rawalpura employees may be men or women. So none of the specific claims about who is sincere or where the men come from can be drawn. None of these follows.

Answer: D

Correct answer: If A is rich, then A is not a beggar.

This is the contrapositive of the statement and so must be true: if all beggars are poor, then anyone who is not poor cannot be a beggar. The others reverse the relation - making all the poor beggars - or draw conclusions the statement does not support.

Answer: B

Correct answer: This is a good book.

The reason offered is that all good books help, and it is used to establish that this book can help. That step works only if the book belongs to the class of good books, so that is what is being taken for granted.

Answer: D

Correct answer: Hitesh perhaps believed in the stories of ghosts.

A man who repeats such a tale as fact very likely gives it some credence himself, so this is the modest inference the statement supports. Nothing is said about how Mohit received it, so his being afraid does not follow, and the statement is one man’s report rather than evidence that ghosts live in peepal trees.

Answer: D

Correct answer: Without hard work, one does not pass.

“One must work hard to pass” makes hard work a necessary condition, so its absence means failure - which is exactly what the conclusion says. It does not make hard work sufficient, so it does not follow that all who work hard pass.
