A Girl Has Many Brothers And Sisters 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?
Hint: Be sure to count the sisters and brothers in total and in terms of their own number of siblings.
4 daughters (sisters) and 3 sons (brothers)
A girl has as many brothers as sisters : If one of the daughters count her siblings, she would count - 3 sisters (3 remaining daughters in the family) and her 3 brothers (3 Sons in the family). So, it makes the statement true that the girl has as many brothers as sisters.
Each brother has only half as many brothers as sisters. This means, when one of the sons count his siblings, it would be 2 brothers (remaining 2 sons of the family) and 4 sisters (All 4 daughters in the family). 2 is the half of 4. It agrees to the condition that
each brother has only half as many brothers as sisters.
Therefore the answer is :
The family has 4 daughters (sisters) and 3 sons (brothers). Did you answer this riddle correctly?
YES NO

Now one of the man needs to call out the color of his hat else they all die in 10 mins. Which man will callout the color of his hat correctly and why?
Hint:
Answer is Man number 2.
Lets start by eliminating men. Man number 4 is at the other end of opaque wall facing other side. There is no way he can see any men or the color of their hat. So he is eliminated. Now man no 3 also cannot see anyone else - he cannot look back and he cannot see beyond wall. So he is eliminated too. Now man number 1 knows the color of man 2 and 3. Now lets say they (2 and 3) were wearing same color hat then man no 1 would know the color of his hat since there are 2 white and 2 black hat. But he keeps mum which means man 2 and 3 are wearing different hat. S0 man number 2 waits for sometime if he does not hear man 1 calling out that means man 2 and 3 are wearing different color hats. Since man 2 knows the color of hat wore by man 3 he know the color of his hat and calls it out. Did you answer this riddle correctly?
