Question

There are 10 cookies in a jar. Each plate can hold 2 cookies. Find the number of plates required.

• A. 2
• B. 8
• C. 6
• D. 5

Answer 1

The correct option is D 5

Let's place 2 cookies on each plate.
Number of cookies left $=10-2=8$
Similarly, we distribute cookies until none is left
$8-2=6$
$6-2=4$
$4-2=2$
$2-2=0$

Since all the cookies are distributed, 5 plates are required to hold 10 cookies.
