Question: How is X related to Y ?

Statements:

  1. Y and Z are children of D who is wife of X.
  2. R's sister X is married to Ys father.

[A]. I alone is sufficient while II alone is not sufficient
[B]. II alone is sufficient while I alone is not sufficient
[C]. Either I or II is sufficient
[D]. Neither I nor II is sufficient
[E]. Both I and II are sufficient

Answer: Option C

Explanation:

From I, we conclude that Y is the child of D who is wife of X i.e. X is Y's father.

From II, X is married to Y's father. This implies that X is Y's mother.

From 1st statement only we find that X is father of y but as per 2nd statement indicates X as mother of Y. This is a contradiction. How to analyze this anomaly?

The correct answer is not expected only the data are sufficient or not to arrive at the answer is required. Hence doesn't matter the relation is different.

I statement shows that x is male person and 2 statement indicates that x is R'S SISTER means female how it can be possible.

Anuradha Chauhan said: (May 11, 2012)  
Option c is correct because statement 1 is alone sufficient to specify relation and 2 statement is also sufficient alone. No matter they are indicating the different relations. or.

BOTH STATEMENTS ARE SUFFICIENT INDEPENDENTLY TO GIVE ANSWER TO WHAT IS ASKED.

Yes, both are true, either 1 or 2 can be used, (consider both statements as separate and non relational statements) then Option C is correct.

If they are considered non relational then how Y and Z are born?

x is father of y means what about D?

Trishul said: (Jul 7, 2015)  
Is it sufficient to only find out that Y is the child of X rather than Y being son or daughter of X?

Both defines a different relationship. Can't conclude it!

Aravind Sai said: (Oct 24, 2020)  
Option D is correct because they haven't mentioned Y's gender.

So, Y can be either son or daughter.
