Conclusion: No reals are Fake and some Fake are Man.
Solution
Answer: 5
Conclusion: No reals are Fake and some Fake are Man
Below diagram represent minimum possible venn diagram of above conclusion
Descriptive way to solve these type of question is to solve option and get the solution:
From Option (a):
Statements: All man are good. Some good are real. Some real are fake. All Fake are bad.
Below diagram represent minimum possible venn diagram of above statement:
Above diagram represent some real are fake.
Hence, above statement will not result given conclusion.
From Option (b):
Statements: Some real are bad. Some bad are good. All goods are Fake. Some goods are Man.
By above statement it is possible to form conclusion but it is not definite.
Hence, above statement will not result in given solution.
From Option (c):
Statements: All real are bad. Some bad are good. Some goods are Fake. All goods are Man.
By above statement it is possible to form conclusion but it is not definite.
Hence, above statement will not result in given solution.
From Option (d):
Statements: All Man are Fake. Some Fake are good. All Fake are bad. Some bad are real
By above statement it is possible to form conclusion but it is not definite.
Hence, above statement will not result in given solution.
From Option (e):
Statements: All Man are Fake. Some Fake are good. All Fake are bad. No bad is real.
As we can see in above diagram, it clearly shows that “No reals are Fake and some Fake are Man”.
Hence, above statement will result in conclusion given in question.
Alternative Method:
Draw a venn diagram of Conclusion given:
As we can see that conclusion consisting negative statement hence, statements must consider negative statement,
Now we will look on option:
A) As there is no negative statement hence, these conclusion can’t result in conclusion.
B) As there is no negative statement hence, these conclusion can’t result in conclusion.
C) As there is no negative statement hence, these conclusion can’t result in conclusion.
D) As there is no negative statement hence, these conclusion can’t result in conclusion.
E) Now we left only option hence it will result in given conclusion. (Here statement of option (e) contain negative statement)
Hence, by taking this intuitive approach we can answer this question.
