## Brothers And Sisters

Difficulty:

A family I know has several children. Each boy in this family has as many suters as brothers but each of the girls has twice as many brothers as sisters. How many brothers and sisters are there?

Since the boys have as many brothers as sisters,
there must be 1 boy more than the number of
girls. If we try 2 and 1, 3 and 2, and 4 and 3,
we will find that 4 boys and 3 girls is the
solution to fulfil the requirement that each girl has
twice as many brothers as sisters.
