Q 3 - Statements:

I. Some mutton are fish.

II. No fish is chicken.

Conclusions:

I. Some fishes are mutton.

II. No mutton is chicken

Answer : A

Explanation

Conclusion I is the immediate inference drawn from first statement. For mediate inference, I + E = O. Therefore, from the pair of statements, conclusion some mutton are not chicken is valid. But this is not our conclusion. Hence only conclusion I follows.

Q 5 - Statements:

I. Some creams are powders.

II. Some powders are lotions.

Conclusions:

I. Some creams are lotions.

II. All lotions are powders.

Answer : D

Explanation

Conclusion II is an immediate inference drawn from second statement and this is not valid as per rule of conversion. Conclusion I is a mediate inference. But as per table of mediate inference, I + I = no result. Hence none of the conclusions follow.

Q 6 - Statements:

I. No cycle is a motorcycle.

II. No motorcar is a motorcycle.

Conclusions:

I. Some cycles are not motorcars.

II. Some motorcycles are motorcars.

Answer : D

Explanation

No cycle is a motorcycle (E) + (no motorcar is motorcycle conversion-) no motorcycle is a motorcar (E) = E + E = no conclusion. Hence conclusion I does not follow. Again, no motorcar is a motorcycle conversion-no motorcycle is a motorcar. Hence conclusion II also does not follow.

Q 7 - Statements:

I. No paper is a pen.

II. All pens are covers.

Conclusions:

I. At least some covers are pens.

II. No cover is a paper.

Answer : A

Q 8 - Statements:

I. Some cricketers are dancers.

II. All dancers are tall.

Conclusions:

I. Some cricketers are tall.

II. All cricketers are tall.

Answer : A

I. All arrows are bows.

II. Some bows are javelins.

Conclusions:

I. Some arrows are javelin.

II. No arrow is javelin.

Answer : C

Explanation

Both the conclusions are mediate inferences. We know from table of mediate inference that A + I = no result. However, this conclusion forms the complementary pairs and comply the conditions, i.e. both the conclusions are I - E type and have the same subject and predicate. Hence either 1 or 2 follows.
