Answer:
b. Rachael’s efficiency.
Explanation:
The 1.2 shows that Rachel is highly efficient as compared to the other employees via a factor of 20%. This can be determined by dividing the rachel output from the standard output i.e.
= 15 ÷ 1.25
= 1.2
The rachel should be efficient as she does high input in the same hour
Therefore the option b is correct
