Question

A professor is expected to cover 16 chapters in an operations management text each semester. One semester the professor dismisses class 30 minutes early every Monday and Friday and is able to cover only 12 chapters. What is the​ professor's efficiency?

Answer 1

Answer:

professor's efficiency is 75%

Explanation:

given data

expected cover = 16 chapters

able to cover = 12 chapters

to find out

the​ professor's efficiency

solution

we know here that when professor works at 100% efficiency

then complete  16 chapter in 1 semester

but here Professor completed only 12 chapter

so for 100% we know 16 chapter that is

100% = 16 chapter

and for x% = 12 chapter

so from above both equation we get x %

x = 100 % × $\frac{12}{16}$

x = 75%

so we can say that professor's efficiency is 75%
