Question

During a certain day, a worker made 81 parts. He usually does 45 parts per day. What was the percent by which he increased the number of parts he usually makes?

Answer 1

Answer:

The answer is 80%.

Step-by-step explanation:

During a certain day, a worker made 81 parts.

He usually does 45 parts per day.

Number of extra parts made = $81-45=36$

The percent by which he increased the number of parts he usually makes can be given as = $\frac{36}{45}\times100$ = 80%

Therefore, on that day, the percent increased by 80%.
