Syllogism Online Quiz

Answer : A

Explanation

All singers are handsome (A) + some handsome are weird (I) = A + I = no conclusion. Hence conclusion II does not follow. Again, some handsome are weird (I) – conversion – some weird are handsome (I). Hence conclusion I follows.

Two statements are given below followed by two conclusions numbered as I and II respectively. Consider the given statements as true even if they seem to be not. After reading all the conclusions conform which of the given conclusions logically follows, disregarding commonly known facts.

Q 2 - Statements:

I. All batteries are torch.

II. No torch is a light.

Conclusions:

I. No battery is a light.

II. At least some torches are batteries.

Answer : E

Explanation

All batteries are torches (A) + no torch is a light (E) = A + E = E = no battery is a light. Hence conclusion I follows. Again, all batteries are torches (A) – conversion – some torches are batteries (I). Hence conclusion II also follows.

Two statements are given below followed by two conclusions numbered as I and II respectively. Consider the given statements as true even if they seem to be not. After reading all the conclusions conform which of the given conclusions logically follows, disregarding commonly known facts.

Q 3 - Statements:

I. Some bananas are flowers.

II. No flower is yellow.

Conclusions:

I. Some flowers are bananas.

II. No banana is yellow

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 banana are not yellow” is valid. But this is not our conclusion. Hence only I follows.

Two statements are given below followed by two conclusions numbered as I and II respectively. Consider the given statements as true even if they seem to be not. After reading all the conclusions conform which of the given conclusions logically follows, disregarding commonly known facts.

Q 4 - Statements:

I. All Pluto are Neptune.

II. Some Neptune are Uranus.

Conclusions:

I. Some Pluto are Uranus.

II. No Pluto is Uranus.

Answer : C

Explanation

Both the conclusions are mediate inferences. We know from table of mediate inference that A &plus 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.

Two statements are given below followed by two conclusions numbered as I and II respectively. Consider the given statements as true even if they seem to be not. After reading all the conclusions conform which of the given conclusions logically follows, disregarding commonly known facts.

Q 5 - Statements:

I. Some cameras are photos.

II. All photos are pictures.

Conclusions:

I. Some cameras are pictures.

II. All cameras are pictures.

Answer : A

Explanation

Both the statements are aligned, i.e. predicate of the first is the subject of the second. From the table of mediate inference, we know that I + A = I. Hence conclusion “some camera are pictures” follows.

Two statements are given below followed by two conclusions numbered as I and II respectively. Consider the given statements as true even if they seem to be not. After reading all the conclusions conform which of the given conclusions logically follows, disregarding commonly known facts.

Q 6 - Statements:

I. No scale is a protractor.

II. No rounder is a protractor.

Conclusions:

I. Some scales are not rounders.

II. Some protractors are rounders.

Answer : D

Explanation

No scale is a protractor (E) + (no rounder is protractorconversion -) no protractor is a rounder (E) = E + E = no conclusion. Hence conclusion I does not follow. Again, no rounder is a protractorconversion - no protractor is a rounder. Hence conclusion II also does not follow.

Two statements are given below followed by two conclusions numbered as I and II respectively. Consider the given statements as true even if they seem to be not. After reading all the conclusions conform which of the given conclusions logically follows, disregarding commonly known facts.

Q 7 - Statements:

I. All jeeps are cars.

II. Some cars are Hondas.

Conclusions:

I. Some Hondas are cars.

II. No jeeps is a Honda.

Answer : A

Explanation

All jeeps are cars (A) + some car are Hondas (I) = A + I = no conclusion. Hence conclusion II does not follow. Again, some cars are Hondas (I) - conversion - some Hondas are car (I). Hence conclusion I follows.

Two statements are given below followed by two conclusions numbered as I and II respectively. Consider the given statements as true even if they seem to be not. After reading all the conclusions conform which of the given conclusions logically follows, disregarding commonly known facts.

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

Explanation

Both the statements are aligned, i.e. predicate of the first is the subject of the second. From the table of mediate inference, we know that I + A = I. Hence conclusion “some cricketers are tall” follow.

Two statements are given below followed by two conclusions numbered as I and II respectively. Consider the given statements as true even if they seem to be not. After reading all the conclusions conform which of the given conclusions logically follows, disregarding commonly known facts.

Q 9 - Statements:

I. Some boundaries are wickets.

II. Some wickets are wide.

Conclusions:

I. Some boundaries are wide.

II. All wide are wickets.

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 conclusion follows.

Two statements are given below followed by two conclusions numbered as I and II respectively. Consider the given statements as true even if they seem to be not. After reading all the conclusions conform which of the given conclusions logically follows, disregarding commonly known facts.

Q 10 - Statements:
