In the questions below some statements are given and these statements are followed by some conclusions. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. Read the conclusions and then decide which of the given conclusions logically follows from the given statements, disregarding commonly known facts.

Syllogism Example 1:

Statements: 

Some desks are benches.

All classes are students.

All benches are classes.

Conclusions:

I. Some desks are classes.

II. All classes are benches.

III. All classes are desks.

A. Only I follows

B. Only I and II follow

C. All follow

D. Only II follows

E. None of these

Syllogism Example 2:

Statements: 

Some bulbs are lights.

Some tubes are bulbs.

No tube is electric.

Conclusions:

I. Some lights are tubes.

II. Some electrics are not tubes.

III. Some bulbs are not electric.

A. I and II follow

B. II and III follow

C. Only III follows.

D. Only I follows.

E. Either II or III follow

Conclusions:

I. Some lights are tubes.

This is a probable conclusion. So, it does not follow.

II. Some electrics are not tubes.

Since no tube is electric, therefore, it is true that some electrics are not tubes.

III. Some bulbs are not electrics.

The bulbs which are tubes are not electric. So, this conclusion follows as well.

Therefore, conclusions II and III follow. So, B is the correct option.

Syllogism Example 3:

Statements: 

All mobiles are cards.

All mobiles are lights.

Conclusions:

I. Few cards are lights.

II. All cards are lights.

A. Only I follows

B. Only II follows

C. Both I and II follow

D. Neither I nor II follows

E. Either I or II follows

Clearly, only conclusion I follows. So, A is the correct option.

Syllogism Example 4:

Statements: 

All mobiles are cards.

All mobiles are lights.

Conclusions:

I. Some cards are mobiles.

II. All lights are cards.

A. Only I follows

B. Only II follows

C. Both I and II follow

D. Neither I nor II follows

E. Either I or II follows

Clearly, only conclusion I follows. So, A is the correct option.

Syllogism Example 5:

Statements: 

All chairs are tables.

Some tables are sofas.

Conclusions:

I. Some chairs are sofas.

II. No table is a sofa.

A. Only I follows

B. Only II follows

C. Both I and II follow

D. Neither I nor II follows

E. Either I or II follows

Syllogisms SE2 Question 5 Venn Diagram

Conclusions:

I. Some chairs are sofas.

This is a probable conclusion. So, it does not follow.

II. No table is a sofa.

Clearly, this conclusion does not follow as well.

Therefore, D is the correct option.

Syllogism Example 6:

Statements: 

All dark is night.

Some dark is black.

Conclusions:

I. All black is night.

II. Some black is not night.

A. Only I follows

B. Only II follows

C. Both I and II follow

D. Neither I nor II follows

E. Either I or II follows

Venn diagram representation of the statements:

Syllogisms SE2 Question 6 Venn Diagram

Conclusions:

I. All black is night.

This is a probable conclusion. So, it does not follow.

II. Some black is not night.

Again, this is a probable conclusion but it complements conclusion I. So, either conclusion I or II follows.

Therefore, E is the correct option.

Syllogism Example 7:

Statements: 

Some mobiles are laptops.

All laptops are grey

No grey is blue.

Conclusions:

I. Some mobiles are grey.

II. Some mobiles are blue.

III. No laptop is blue.

A. Only I follows

B. Only III follows

C. Both I and II follow

D. Both I and III follow

E. Both II and III follow

Venn diagram representation of the statements:

Syllogisms SE2 Question 7 Venn Diagram

Clearly, conclusions I and III follow. So, D is the correct option.

Syllogism Example 8:

Statements: 

Some banks are papers.

Some papers are dresses.

Some dresses are chairs.

Conclusions:

I. Some banks are dresses.

II. Some papers are chairs.

III. Some banks are chairs.

A. None follows

B. Only I follows

C. Only II follows

D. Only III follows

E. All follow
