Question

A store has $660$ books in stock. If $30$ percent of these books are on sale, how many books are not on sale?

• A. $462$
• B. $562$
• C. $472$
• D. $572$

Answer 1

The correct option is A $462$

Total number of books in stock are $660$. Given that $30$ percent of these books are on sale. So $70$ percent of books are not on sale.

So , number of books which are not on sale is $\frac{70}{100}\times 660=462$.
