All monkeys are donkeys. Some donkeys are horses. No horse is a monkey.
Conclusions:
1. Some horses are monkeys.
2. Some donkeys are not monkeys
Answer (Detailed Solution Below)
Syllogism Question 1 Detailed Solution
The least possible venn diagram is shown below,
Conclusions:
1. Some horses are monkeys → False (No horse is a monkey implies that some horses can't be monkeys).
2. Some donkeys are not monkeys → True (All monkeys are donkeys, some donkeys are horses and no horse is a monkey implies that some of those donkeys which are horses are not monkeys).
Hence, the correct answer is "Option 1".
Syllogism Question 2:
In the following question statements are given and these statements are followed by 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.

The possible diagram according to the given statement:
Conclusions :
I. Some writers are answers → True (Because the given statement is some answers are writers so, some writers are also answers)
II. Some poets are questions → False ( Because no direct relationship is given between poets and questions so it may be possible but not defined)
III. All the questions are poets → False (Because no direct relationship is given between questions and poets so it may be possible but not defined)
IV. Some poets are answers → True (Because some answers are writers and all the writers are poets so some poets are also answers Because some answers are writers and all the writers are poets so, some poets are also answers)
So, Only I and IV follow.
Hence, the correct answer is "option (2)".
Syllogism Question 3:
consider the statements and conclusions given below and find out which of the two conclusions logically follows from the given statements.

The Venn Diagram for the given data:
Conclusions:
I, All women are parrots → True (All women are flowers and all flowers are parrots which implies all women are parrots.)
II. All parrots are women → False (All women are flowers and all flowers are parrots which implies some parrots are women.)
Hence, "only conclusion I follow".
Syllogism Question 4:
Which of the conclusions logically follow(s) from the given statements?
Statements:
Some players are singers.
All singers are tall.
Conclusions:
I. Some players are tall.
II. All players are tall.
Answer (Detailed Solution Below)
Syllogism Question 4 Detailed Solution
Given Statements:
Some players are singers.
All singers are tall.
The least possible Venn diagram for the given statement is:
Conclusions:
I. Some players are tall - True (Since some players are singers, and all singers are tall, it logically follows that some players must also be tall. The overlapping region of 'Players' and 'Singers' is within the 'Tall' circle).
II. All players are tall - False (While some players are tall, there is no information to suggest that ALL players are tall. The Venn diagram shows a portion of 'Players' that is outside the 'Tall' circle).
So, Only conclusion I follows.
Hence, the correct answer is "Option 2".

Syllogism Question 7 Detailed Solution
Download Solution PDFConcept:
1) We have to check the conclusions are 100% match with the statement. If the conclusion is 100% match with the given statement then the conclusion is true. If there is a 1% chance of not following the statement then the conclusion is considered to be false.
2) The possibility case can be considered to be "false" in "definite case".
3) In Possibility case, either "can" or "possible" word must be present.
The least possible Venn diagram for the given statements is as follows:
Conclusions:
I. Some bags are not bottle → False (There is no direct relation given between bottle and bags so it can be possible but not definite, hence, false)
II. Some plastic are not bags → False (As "Some bags are plastic" given so some plastic can be bags it can be possible but some plastic are not bags it is not definite, hence, false)
Hence, the correct answer is "None follows".
Additional Information
Note: The answer here will not be “Neither conclusion I nor II follows”.
Don’t get confused as in the “neither-nor case” the subject and predicate in both the conclusions must be the same.

III. Some Z are Y.
Answer (Detailed Solution Below)
Syllogism Question 8 Detailed Solution
Download Solution PDFGiven Statements:
I. All Z are Y.
II. Some Y are B.
The least possible Venn diagram for the given statement is:
Conclusions:
Conclusion I: False ("Some B are not Z" is not true because there is no negative relation between B and Z. It may be possible but not definitely true. In syllogism, we take the definite cases as true. So this conclusion not follow.)
Conclusion II: False ("Some Y are not Z" is not true because there is no negative relation between Y and Z. It may be possible but not definitely true. So, this conclusion also not follow.)
Conclusion III: True ("Some Z are Y" is true because when all Z are Y is given then "some Z are Y" is also true. Please note that "some" is a subset of "all". For example, when all boys are male, then "some boys are male" is also true.)
So, Only conclusion III follows.
Hence, the correct answer is "Option 3".
Mistake PointsNegative Conclusions will never be definitely true when a given statement is positive.
Here, Conclusion I & II is negative, so it will be true in possibility only.
statements is true, even if they appear to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements beyond reasonable doubt.

Syllogism Question 13 Detailed Solution
Download Solution PDFAll + No and Some + Some not are not complementary pairs.
In case of Some + Some not, the following condition is not fulfilled:
The term Either or denotes that if one condition is true then the second condition is would be automatically false.
But in case of Some and some not, both the conditions can be true at a time.
Conditions of Either-or case:
1. The elements should be the same in both the statements.
2. Both the conclusions should be false individually.
3. One conclusion should be positive and one conclusion should be negative (Complementary pair).
The two complementary pairs are:
1) All + Some not
2) No + Some
The least possible diagram for the given statements is as follows:
Conclusions:
I. Some colleges are houses → False (There is no direct relation given between colleges and houses so it can be possible but not definite, hence, false)
II. Some colleges are not houses → False (There is no direct relation given between colleges and houses so it can be possible but not definite, hence, false)
Hence, the correct answer is "Neither I nor II follows"

2. Some plumbers are not cooks.
3. Some men are not cooks.
Answer (Detailed Solution Below)
Syllogism Question 15 Detailed Solution
Download Solution PDFThe least possible Venn diagram is:
Conclusions:
1. Some plumbers are cooks. → False (As, there is no definite relation between plumbers and cooks. Hence, false)
2. Some plumbers are not cooks. → False (As, there is no definite relation between plumbers and cooks. Hence, false)
3. Some men are not cooks. → True (As, Some men are electricians and No electrician is a cook → Some men who are electricians are not cooks)
Hence, only conclusion 3 follows.
Confusion Points 1. When There is no relation given between the two elements, in that case, we cannot define their relation so here between a plumber and cook we cannot define relation so it will not follow here.
