Question

A teacher bought a packet of $17$ batteries. Each calculator uses $3$ batteries. How many calculators can the teacher fill with batteries?

• A. $7$
• B. $10$
• C. $5$

Answer 1

The correct option is C $5$

Total number of batteries $=17$
Number of batteries used for each calculator $=3$
To find how many calculators can the teacher fill with batteries, divide the total number of batteries by the number of batteries used for each calculator.
We get, divide $17$ by $3$

Quotient = 5
Remainder = 2
Now, the teacher can't fill a calculator using the remaining $2$ batteries.
Hence, We Just drop it.
Therefore, the teacher can fill $5$ calculators only.
