Question

There are 20 dowels. All bevels are dowels. All dowels are swivels. There are 12 bevels. There are 30 swivels. How many swivels are not bevels or dowels?

Answer 1

10

Explanation:

Given that all bevels are dowels, where there are 12 bevels and 20 dowels, it means there are 12 bevels that are dowels and 8 dowels that are not bevels.

Furthermore, if all dowels are swivels, and there are 30 swivels then the number of swivels that are neither bevels nor dowels

= 30 - 20

= 10

There are 10 swivels that are not bevels or dowels.
