The number of brothers Anna has is twice the number of sisters Anna has.


The number of sisters Anna has is twice the number of brothers Anna has.


Does Anna have any siblings?


No, Anna doesn't have any siblings. This is a clever riddle that plays with words.

If Anna had brothers or sisters, one of the two statements would be true, but not both at the same time. For example, if Anna had two brothers and one sister, then the first statement would be true, but the second would not. Similarly, if Anna had one brother and two sisters, the second statement would be true, but not the first.

Since both statements are given to be true, it leads to a contradiction, and therefore, the only logical conclusion is that Anna has neither brothers nor sisters, i.e., no siblings.
