Solutions (1 to 8)

1) Answer (e)

Some casual are formal.
All formal are expensive. Hence, some casuals are expensive.
All expensive are elegant. Hence, all formals are elegant and some casuals are elegant.
Therefore, both I and II follow.

Some red are paints.This conclusion can be drawn as apparent from Venn diagram.
All red are roses.This is obviously a wrong conclusion.
Hence, only I follows.

3) Answer (d)

The data can be intrepreted in Venn diagram from as:

Some towns are rural. We cannot say this with surety and this conclusion can be contradicted.
All rural are towns.This definitely cannot be concluded from Venn diagram.
Hence, both conclusion I and II do not follow.

4) Answer (d)

Data can be intrepreted in Venn diagram form as:

Some tablets are bitter. This conclusion cannot be drawn from the Venn diagram.
No medicines is a tonic.This conclusion also cannot be drawn.
Both I and II do not follow.
Option D is correct option.

5) Answer (b)

Data can be intrepreted in Venn diagram form as:

Some incomes are tangible. The income and tangibles are disjoint sets. Hence, conclusion drawn is incorrect.

At least some perks are salaries. This conclusion is correct. There is intersection betweem perks and salaries set.

6) Answer (b)

No parachute is an airplane and all airplanes are helicopters doesn’t give an indication about the relation between parachutes and helicopters. So, all parachutes are helicopters is not contradicted in the statements.

7) Answer (e)

From the given statements, no glider is an airplane is implied but no relation is established between gliders and helicopters. So, all gliders being helicopters is a possibility.

8) Answer (a)

Some mails are chats. There is a possibility that all mails are chats. All updates are chats. So, if mails is a subset of updates, which in turn is a subset of chats, the conditions still hold true. So, conclusion I follows. Conclusion II is not necessarily true as there might be some intersection between mails and updates.
