Question

if one father have 4 daughter and they have each brother how many children he have? tell me fast​

Answer 1

First of all there are few informations missing from the question itself.

Anyway let’s try to answer.

As the questions contains the infomation "a person HAD 4 daughters" which is in past and question asked "how many children DOES the person have ?" is in present.

So it simply means that those 4 daughter have passed away in past and in present they are no more. (Unfortunately)

So at present he doesn't have any daughter.

Now those daughters might had belong to single father (that person)

but

Case-1 :

all 4 daugthers belong to 4 different mothers separately.

Case-2 :

2 belong to 1 mother and rest 2 belong to 2 different mothers separately.

Like that few more cases will arrive and make this question unneccesarily complicated.

So, it is better to assume that all are from single mother and single father to keep it simple.

For single mother and father (assumed) they HAD one brother.

Now it is written that “each daughter HAD a brother”, which doesn't mean that the Son is also dead.

If it would have been written like "The person HAD a son", then it means his Son also died in past.

So, if it not clear that someone is dead or alive at present then let's be kind enough to assume that he is alive.

So, with the assumptions which were crucial to complete the question, the total number of children the person has (of course we are talking about present) is 1.

And it is his son only.
