Syllogism Online Quiz

Answer : A

Explanation

All pictures are credits (A) – conversion – some credits are pictures (I). Hence conclusion I follows. No figure is a picture (E) + all pictures are credits (A) = E + A = O ∗ = some credits are not figures. Hence conclusion II 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 2 - Statements:

I. Some students are bad.

II. Some bad are good.

Conclusions:

I. Some students are good.

II. All good are bad.

Answer : D

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 entertainers are boring.

II. All boring are dusty.

Conclusions:

I. Some entertainers are dusty.

II. All entertainers are dusty.

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 entertainers are dusty” 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 pencil are pens.

II. Some pens are rubbers.

Conclusions:

I. Some pencils are rubbers.

II. No pencil is rubber.

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.

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 balls are bats.

II. All bats are gloves.

Conclusions:

I. Some ball are gloves.

II. At least some gloves are bat.

Answer : E

Explanation

Some balls are bats (I) + all bats are gloves (A) = I + A = I = some ball are gloves. Hence conclusion I follows. Again all bats are gloves -conversion - some gloves are bat. 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 6 - Statements:

I. All granites are marbles.

II. Some marbles are tiles.

Conclusions:

I. Some tiles are marbles.

II. No granite is a tile.

Answer : A

Explanation

All granites are marbles (A) + some marbles are tiles (I) = A + I = no conclusion. Hence conclusion II does not follow. Again, some marbles are tiles (I) - conversion - some tiles are marbles (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 7 - Statements:

I. Some numbers are digits.

II. No digit is a letter.

Conclusions:

I. No number is a letter.

II. At least some numbers are letters.

Answer : C

Explanation

Some numbers are digits (I) + no digit is a letter (E) = I + E = O = some numbers are not letters. But conclusion I and II make a complementary pair (I - E). Hence either I or II follows. So option C is the right answer.

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 ropes are tubes.

II. Some tubes are mats.

Conclusions:

I. Some tubes are ropes.

II. Some mats are tubes.

Answer : E

Explanation

Both the conclusions are immediate inferences drawn from statements and follow the rule of conversion.
