Question

Books are on sale for $\$7.$ Peter has $\$30$ in his wallet. How many books can he buy?

• A. $2$
• B. $4$
• C. $7$

Answer 1

The correct option is B $4$

Total money peter has $=\$30$
Price of one book $=\$7$
To find how many books he can buy, divide the total money by price of one book.
We get, divide $30$ by $7$

Quotient = 4
Remainder = 2
Now, Peter can’t buy a book using the remaining $\$2$
Hence, We Just drop it.
Therefore, Peter can buy $4$ books.
