Three statements are given below followed by three conclusions numbered I, II and III. You have to take the given statements to be true even if they seem to be at variance from the commonly known facts and decide which of the given conclusions logically follows from the given statements.
Statements: All dolls are windows. All bottles are windows. All cars are bottles.
Conclusions:
I. All cars are windows
II. Some cars are dolls.
III. Some windows are cars.
Three statements are given below followed by three conclusions numbered I, II and III. You have to take the given statements to be true even if they seem to be at variance from the commonly known facts and decide which of the given conclusions logically follows from the given statements.
Statements: All dolls are windows. All bottles are windows. All cars are bottles.
Conclusions:
I. All cars are windows
II. Some cars are dolls.
III. Some windows are cars.
Solution
"All dolls are windows. All bottles are windows. All cars are bottles."
We can make a Venn diagram to make the relationship clear:
Now, just check all the statements/conclusions
"All cars are windows": True
"Some cars are dolls": False
"Some windows are cars": True
Note: We can construct a case where II is also true:
But since we know that I and III are 100% true, and there is no option that says all the 3 statements are true, there's no need to go further.
For future cases, if a question asks what MUST be true, or what can be concluded, only include those options that are true 100% of the time. If a question asks what CAN be true, then include statements like 2.
