IBPS Syllogism and Logical Reasoning 2

Question 1

Statements: All roses are flowers. Some flowers are red. Conclusions: I. Some roses are red. II. All flowers are roses. Which conclusion(s) follow?

Accepted Answer

Neither I nor II follows

Answer

Some flowers are red does not mean some roses are red; 'All flowers are roses' reverses a one-way statement, so neither conclusion follows.

Question 2

Statements: No pen is a pencil. All pencils are stationery. Conclusions: I. No pen is stationery. II. Some stationery are not pens. Which conclusion(s) follow?

Accepted Answer

Only II follows

Answer

We can only confirm that the pencils (a subset of stationery) are not pens, so some stationery are not pens; we cannot say NO pen is stationery.

Question 3

Statements: All cats are animals. All dogs are animals. Conclusions: I. All cats are dogs. II. Some animals are cats. Which conclusion(s) follow?

Accepted Answer

Only II follows

Answer

Both cats and dogs being animals does not link cats to dogs, but conversion of 'All cats are animals' gives 'Some animals are cats.'

Question 4

Statements: Some books are novels. All novels are fiction. Conclusions: I. Some books are fiction. II. All fiction are novels. Which conclusion(s) follow?

Accepted Answer

Only I follows

Answer

Some books are novels and all novels are fiction, so some books are fiction; reversing 'All novels are fiction' is invalid.

Question 5

In a coded language, BANK is written as YZMW. What is LOAN coded as?

Accepted Answer

OLZM

Answer

Each letter is replaced by its mirror opposite (A↔Z, B↔Y, …), so L→O, O→L, A→Z, N→M giving OLZM.
