A woman gives a beggar 1 dollar and 32 cents; the woman is the beggar’s sister, but the beggar is not the woman’s brother. How come?
both are sisters ,as both male and female versions called as beggar,
The beggar can be female, so she can't be the brother of that women.
Beggar and women are sisters as the question itself says beggar is not a women's brother so it states she is definitely a female i.e her sister.
They are talking about two different women.
