Question

A publisher estimates that 8 of every 50 books become national best sellers. What's percentage of the books do not become national best sellers

Answer 1

We conclude that 84% of books are not best-sellers.

Explanation:

A publisher estimates that 8 of every 50 books become national best-sellers.

Means 16% of books are best sellers.

• Because 16% of 50 books = 8 ∵ 16/100 × 50 = 8

Thus,

Bestseller books = 16%

Books that are not national best sellers = 100% -16% = 84%

Therefore, we conclude that 84% of books are not best-sellers.
