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