Practice Logical Reasoning questions on Statement and Conclusion, covering statements, implied conclusions, logical deductions, and determining which conclusions necessarily follow from the given information. Takes about 20–25 minutes and is useful for placement, TCS NQT, SSC, banking and MBA entrance exams.
Question 1
Assume that there are three statements followed by several conclusions. You have to take the given statements to be true, even if they seem to be at variance from commonly-known facts and then decide which of the given conclusion/s logically follows.
Statements : I. All Pens are Tables
II. Some tables are rulers.
III. Some rulers are chalk.
Conclusion : I. Some tables are chalk.
II. Some pens are chalk.
III. Some rulers are pens.
IV. Some chalk are rulers
Statements : I. All Pens are Tables
II. Some tables are rulers.
III. Some rulers are chalk.
Conclusion : I. Some tables are chalk.
II. Some pens are chalk.
III. Some rulers are pens.
IV. Some chalk are rulers
Explanation
Only conclusion IV follows, because 'Some rulers are chalk' can be reversed to 'Some chalk are rulers'. Conclusions I, II and III need links between tables and chalk, pens and chalk, and rulers and pens, which the statements do not give.
Option B is wrong because conclusions I and II need links between tables and chalk and between pens and chalk, but two 'some' statements in a row give no such link.
Option C is wrong because conclusion III is not certain, since the tables that are rulers need not be pens.
Option D is wrong because conclusions I, II and III all rely on links that the statements do not provide.
Option B is wrong because conclusions I and II need links between tables and chalk and between pens and chalk, but two 'some' statements in a row give no such link.
Option C is wrong because conclusion III is not certain, since the tables that are rulers need not be pens.
Option D is wrong because conclusions I, II and III all rely on links that the statements do not provide.
Question 2
Assume the given statements are true, even if they seem to be at variance from commonly known facts, then decide which of the given conclusion/s logically follows.
Statements :
I. Some cars can fly
II. Rama is a car.
Conclusion :
I. Rama can fly
II. Rama cannot fly
III. Rama can dance
IV. Rama can swim
Statements :
I. Some cars can fly
II. Rama is a car.
Conclusion :
I. Rama can fly
II. Rama cannot fly
III. Rama can dance
IV. Rama can swim
Explanation
Some cars can fly and Rama is a car, but it is not stated that Rama is one of the cars that fly. So Rama either can fly or cannot fly, and exactly one of these two is true. Hence either I or II follows. Conclusions III and IV have no connection with the given statements.
Option A is wrong because conclusion I alone is not certain, since Rama may be a car that cannot fly.
Option C is wrong because conclusion III (Rama can dance) has no link with the statements.
Option D is wrong because conclusions I and II contradict each other, and III and IV have no basis, so all four cannot follow.
Option A is wrong because conclusion I alone is not certain, since Rama may be a car that cannot fly.
Option C is wrong because conclusion III (Rama can dance) has no link with the statements.
Option D is wrong because conclusions I and II contradict each other, and III and IV have no basis, so all four cannot follow.
Question 3

The 5G broadband services are provided only by Company X.
Explanation
The statement says oligopoly is characterised by competition, while the 5G broadband services are provided only by Company X, so there is no competition. A market with a single provider is a monopoly, so the conclusion that Company X's market is monopolistic follows.
