Brothers and Sisters I have None ::

Looking at a portrait of a man, Harsh said, "His mother is the wife of my father's son. Brothers and sisters I have none." At whose portrait was Harsh looking? 

D is father of A and grandfather of F. So, A is father of F. 

Thus. D and A are the two fathers. C is the sister of F So. C is the daughter of A. 

Since there is only one mother, it is evident that E is the wife of A and hence the mother of C and F. 

So, B is brother of A There are three brothers. So. F is the brother of C. 

 Clearly, A is E's Husband.

E is the daughter of A and F is the mother of E So, A is the father of E and hence the husband of F. Now,

D is the daughter of F So. D and E are the daughters of A and F Also. A is the son of C. 

Now, only B remains Thus. B and C are the parents of A. 

Clearly. B and C are the parents of the couple 

The sex of A is not known. So. neither (a) nor (b) is definitely true. Clearly, D is the grandmother of A and F. 

A is the brother of B and B is the brother of C. So, C may be the brother or sister of A. 

C is D's daughter and D is B's son. So, D is the brother of C. E is a male married to C. 

So, E is the husband of C, whose brother is D. So, D is the brother-in-law of E. 

Daughter of your father — Your sister. So, the person's mother is woman's sister or the woman is person's aunt. 

Anuj's daughter's mother — Anuj's wife ;

Anju's wife's father - Anuj's father-in-law; 

Father-in-law's son — Anuj's brother-in-law

So, Manish is Anuj's brother-in-law 

Only son of Neena's father-in-law Mahipal Neena's husband. So, Raman is Neena's husband and Anita and Hindu are his daughters. 

 Thus, Bindu is the grand daughter of Mahipal.
