A Riddle About Brothers and Sisters
A riddle...
A girl has as many brothers as sisters, but each brother has only half as many brothers as sisters. How many brothers and sisters are there in the family?
Explanation:
Let's denote the number of brothers as B and the number of sisters as S. Based on the riddle:
Number of brothers = Number of sisters
Each brother has only half as many brothers as sisters:
Each brother (B) has B / 2 sisters
Since the number of brothers and sisters is the same, we can create the equation:
B = S
Substitute the second condition into the first equation:
B = S/2
By solving these two equations simultaneously, we find:
S = 4 and B = 3
