This question was asked on web radio.
A couple has 3 sons..
Each son has a sister, a wife and a child.
How many people are there in the family ??
Answer
A couple has 3 sons. Each one of them has a sister.
This is possible only when all of the sons have only one sister.
That means, couple has 4 children. 3 sons and 1 daughter
Total number of family members, 2 + 4 = 6.
Now each son has a wife and a child.
That means, 1st son =2 members
Same way, 3 sons = 6 members.
First we got number of members as 6
Now again 6 members.
Adding both the equation, we get numbers of family members = 12.
