Question

An ice cream machine produced 52 ice creams per minute. After reconditioning, its speed increased to 65 ice creams per minute. By what percent did the speed of the machine increase?

Answer 1

Answer:25 %

Step-by-step explanation:

Given

Earlier machine was producing 52 ice cream per minute and

Now it is Producing 65 ice creams per minute

So percentage increase of the machine $=\frac{\text{final-Initial}}{\text{Initial}}\times 100$

$=\frac{65-52}{52}\times 100$

$=\frac{13}{52}\times 100$

$=\frac{1}{4}\times 100=25\ \%$

So there is increase of 25 % in speed
