Logical Reasoning - Statement and Assumption - Discussion

In each question below is given a statement followed by two assumptions numbered I and II. You have to consider the statement and the following assumptions and decide which of the assumptions is implicit in the statement.

Give answer

  • (A) If only assumption I is implicit
  • (B) If only assumption II is implicit
  • (C) If either I or II is implicit
  • (D) If neither I nor II is implicit
  • (E) If both I and II are implicit.


Statement: Money is the root cause of all the problems in a family.


  1. Every problem is caused by something.
  2. There are always some problems in a family.

[A]. Only assumption I is implicit
[B]. Only assumption II is implicit
[C]. Either I or II is implicit
[D]. Neither I nor II is implicit
[E]. Both I and II are implicit

Answer: Option D


The statement mentions the cause of family problems and does not deal with all the problems. So, I is not implicit. Also, it is mentioned that money is the cause of family problems. But this does not mean that problems always exist in a family. So, II is also not implicit.

Why is A incorrect? The statement states the cause of "all problems" in a family... assumption I. mentions "every problem" is caused by something... that something according to the statement could be "money" ... so why is A incorrect?

Yes, why A is incorrect ?

Every problem is caused by something.

Both 1 and II should be correct II because money is always there in the family though little so problems are always present and I is correct as it is mention there "all problems".

Both I and II are not correct because both are directly not related with question.

Every problem is caused by something. Boss think that I have gained less marks in your test that means I have done something wrong to write answer hence I have got less marks or problem, hence my answer I think is right one.

It is clearly stated the ALL problems have money as the root cause. Hence, it follows that all problems have something as the cause and that something is money. To say otherwise is saying money is not something.

I think the first option is right.

Money is the root cause of all the problems in a family.

So obviously Every problem is caused by something.

Option 2 is not related because. Problems are caused by something, that doesn't imply every family should have a problem.

So I think option 1 is right.

I think II is also implicit.

Families have money. Money is the root cause of all problems. Some families with money must have problems.

Money is the root cause of all the problems. So, the problems are caused by money. Money is definitely some'thing'. So, if problems are caused by money, they are definitely caused by something. Option 1 is definitely implied.

If money is root cause of all problems in a family, every family has money so every family has problems.

I'm not sure I like the reasoning but here's the best I can see.

Not one because it says "All problems" and not just family problems. So a problem with, say, a job might not be due to money.

Not every family has problems, I suppose. Just because they have money, doesn't mean that the money WILL cause a problem, just that if there is a family problem, it'll be caused by the money.

Kind of like saying "All wrecks are caused by cars". Just because you have a car, it doesn't mean that you most definitely will be in a wreck.

What is implicit?

Nick Dunkin said: (Jun 26, 2015)  
I got this wrong, but I think the test answer is correct for the following reasons:

1) We don't know that all problems are caused by something. We only know that family problems are caused by something.

3) Some families may have no problems.

I is definitely implicit. Remove that assumption and you will find that the statement doesn't hold true anymore because it says all problems in a family are caused by money.

Gaurav said: (Jul 22, 2016)  
I think both I and II are implicit.

Because it is the universal truth there is always a cause for every problem.

And there is always some sort of unfinished talk or a problem that arises in a family.

The answer is E.

Why not option 1?

Kevin said: (Oct 29, 2019)  
After reading the answer by @Neeraj I felt enlightened!

The statement: Given a family F, suppose Pf is a problem with the family and Rpf is the root cause of the problem. Then it is necessarily true that R is money.

I: There exists a cause c for any problem p.
II: There exists a problem p for any family f.

So from this, I can see that my usual understanding of "implicit assumption" is OK for this problem. I am not sure yet if I have been missing similar logic issues in other of these questions I've been attempting to analyze.

I also don't understand why A is incorrect. It's still there, like it's still true though, right? Doesn't every problem originate somewhere? Please clarify again, thanks!
