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. 
So, lady on the stage is Monika’s daughter.
