Regarding time management (Question:150034.0)

can you please tell me how much time is taken by the topper to solve these question?

Question:

DIRECTIONS: These questions are based on the following information:


Eight members of a family, A through H are sitting around a circular table.


The following information is known about them:


(i) There are three married couples in the family.

(ii) One of A’s sons is sitting opposite him while the other is adjacent to him.

(iii) H’s sister-in-law is B who is sitting to the immediate right of H’s father-in-law.

(iv) The number of females in the family is less than the number of males in the family.

(v) Two of the married couples have two children each.

(vi) C, who is the eldest male in the family, is sitting third to the left of his wife.

(vii) F, the youngest, is not G’s son and is sitting adjacent to H.

(viii) H is the aunt of E, who is sitting three places away from G.

Who is C’s son?


Options:
A) A
B) E
C) D
D) G
E) None of the above
Solution:

Ans: (d) As there are three married couples and two of them have two children each, the eight member family is possible only with the following structure.

 

From (iv) we can say that there are 3 females and 5 males in the family. 

From (iii) we can say that H is from the second generation, as H has a sister-in-law as well as father-in-law. 

From (viii) we know that H is a female. Thus, one of the siblings in the second generation is male and the other is a females. Now from (ii) A is male, and has two sons. 

As H is the aunt of E, 

A cannot be H’s husband as only one of the two couples in the second generation has children. 

As F is the youngest and he is not G’s son, he must be A’s son. 

Thus, from (ii), (iii), (vi) and (viii) we have 


M → Male 

F → Female 

We do not have any information about D and G so let us leave it here. 

Now, from (iii) and (vi) we get following arrangement. 

 

Now, only two seats that are opposite to each other are vacant. Thus, from (ii), A cannot be to the immediate

right of B. 

Thus, we get the following arrangement. 


Since F is A’s son and F is adjacent to both H and A from (vii) and from (ii), Thus 


From (viii), E is three places away from G. 

So, we get the following arrangement. 

 

Thus, D is C’s wife and G is H’s husband. 

G is C’s son.
