Lana71 [14]

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%.
