Discussion Forum : Logical Problems - Type 4 (Q.No. 1)
Directions to Solve
The logic problems in this set present you with three true statements: Fact 1, Fact 2, and Fact 3. Then, you are given three more statements (labeled I, II, and III), and you must determine which of these, if any, is also a fact. One or two of the statements could be true; all of the statements could be true; or none of the statements could be true. Choose your answer based solely on the information given in the first three facts.

1.
Fact 1: All dogs like to run.
Fact 2: Some dogs like to swim.
Fact 3: Some dogs look like their masters.
If the first three statements are facts, which of the following statements must also be a fact?
I: All dogs who like to swim look like their masters.
II: Dogs who like to swim also like to run.
III: Dogs who like to run do not look like their masters.
I only
II only
II and III only
None of the statements is a known fact.
Answer: Option
Explanation:
Statement II is the only true statement. Since all dogs like to run, then the ones who like to swim also like to run. There is no support for statement I or statement III.

@Renuka.

If it was 'Some Dogs who like to run do not look like their masters. ' then what you said would be correct. But here it is 'Dogs who like to run do not look like their masters. 'All dogs like to run. So Dogs who like to run means All dogs. Here given, some dogs look like their masters. So ' (All) Dogs who like to run do not look like their masters. ' is wrong.

@Renuka.

Only consider whats given. It is evident that some dogs don't look like their masters but that's not mentioned anywhere. So don't consider that.

"Some dogs look like their masters means some of the dogs doesn't look like their masters."

In deductions this is NEVER a valid conclusion.
Some are doesn't mean others aren't.

e.g) All indians like ice cream. Some indians like softee. Who said the others hate softee? there is no info to support it.

All dogs like to run, Some dogs look like their masters means some of the dogs doesn't look like their masters.

So,
Dogs who like to run do not look like their masters. Also true.

Please explain what I'm thinking correct are not?
