Types of questions asked from Blood Relations:
1.   Based on Dialogue or Conversation
2.   Based on Puzzles
3.   Based on Symbolically coded

Based on Conversation ro Dialogue-
In this type of questions, the one person talking to or doing chit-chat with other person giving information by pointing to some picture or person.
Example:- Pointing to a lady on the stage, Monika said, “She is the sister of the son of the wife of my husband.” How is the lady related to Monika?
Solution: Find who you can easily relate to and be that person-then go about creating one relation after another. In this question, be Monika-then start from the end of the sentence.
“My husband” = Monika’s husband
‘Wife of my husband’ = is me = Monika
‘Son of the wife of my husband’ = My Son
‘Sister of the Son of the wife of my Husband’ = My Son’s Sister = My daughter ‘She’ is the sister of the son of the wife of my husband’ = the lady on the stage = the lady being pointed out = my daughter.
