A researcher estimates that `10%` of the children in the world are between the ages of 8 and 18 and dislike soccer, and that `50%` of the children who like soccer are between the ages of 8 and 18. If `40%` of the children in the world are between the ages of 8 and 18, what percentage of children in the world are under age 8 and dislike the game of soccer? (Assume all children are between the ages of 0 and 18.)

Answer

`30%`
