Solve the Puzzle: Siblings in Family

In the Siblings in Family Puzzle, we have a family. In a particular family, each boy has as many brothers as the sisters, but each girl has twice as many brothers as the sisters. How many siblings are there in the family?

Solution

Here we have the solution for Siblings in Family Puzzle –

Let us denote the number of boys as ‘p’ and the number of girls as ‘q’.

The first statement says that each boy has an equal number of brothers and sisters

(p – 1) = q

p – q = 1 ——-> Equation (a)

The second statement says that every girl has twice as many brothers than sisters.

2 (q – 1) = p

2q – p = 2 ——->Equation (b)

By solving Equation (a) and Equation (b)

We get ‘q’ as 3 and ‘p’ as 4.

Therefore, there are 4 boys and 3 girls in the family.
