Logical 22 - Blood Relations

This is Relation Puzzle. Here the mutual blood relations of more than two persons are mentioned. We have to analyze the given information, work out a family chart and then answer the given questions.

Question 1:
A family has a man, his wife, their four sons and their wives. The family of every son also has 3 sons and one daughter. Find out the total number of male members in the whole family.
The male members in the family are,
  1. the man himself
  2. his four sons
  3. his 3 x 4 = 12 grandsons
So, the total male members are 1 + 4 + 12 = 17. 

Question 2:
A and B are brothers. C and D are sisters. A's son is D's brother. How is B relates to C?
Clearly, B is the brother of A. A's son is D's brother. This means D is the daughter of A. 
Since, C and D are sisters, C is also the daughter of A.
So, B is the Uncle of C.

Question 3:
A is B's sister. C is B's mother. D is C's father. E is D's mother. Then, how is A related to D?
A is the sister of B and B is the son/daughter of C. So, A is the daughter of C. Also, D is the father of C. Thus, A is the grand daughter of D. 

Question 4:
Ravi is son of Aman's father's sister. Sahil is son of Dhivya who is mother of Gaurav and grandmother of Aman. Ashok is father of Tanya and grandfather of Ravi. Divya is wife of Ashok.
How is Ravi related to Divya?
Divya is wife of Ashok and Ashok is grandfather of Ravi. So, Ravi is Divya's Grandson. 

Question 5:
How is Gaurav's wife related to Tanya?
Tanya is Ashok's daughter. Gaurav is Divya's son and Ashok is Divya's husband. So, Gaurav is Tanya's brother and his wife is Tanya's Sister-in-law. 


Time to Think:

In a joint family, there are father, mother, 3 married sons and one unmarried daughter. Of the sons, two have 2 daughters each and one has a son. How many female members are there in the family?
