Question

Joe's bakery is known for its handmade donuts. If 40 donuts were sold on day 1 and 100 donuts on day 2, what is the percentage increase in the number of donuts sold on day 2 compared to day 1?

• A. 125%
• B. 50%
• C. 150%
• D. 100%

Answer 1

The correct option is C 150%

On day $1,40$ donuts were sold.

On day $2,100$ donuts were sold.

Percentage increase in the number of donuts sold on day $2$ compared to day $1$
$=\frac{Numberofdonutssoldonday2-numberofdonutssoldonday1}{Numberofdonutssoldonday1}\times 100\%$
$=\frac{100-40}{40}\times 100\%$
$=\frac{60}{40}\times 100\%$
$=150\%$
