Answer:
The correct option is C, the increase in productivity is 18.75%
Step-by-step explanation:
The quantity before installing the new process=(100%-20%)*300
That is 80% of 300units=240units
The quantity after installation is (100%-5%)*300
That is 95% of 300=285units
The increase is 45units(285-240)
Hence % increase =45/240*100=18.75%
That is 18.75% increase in production output due to the installation of the new process
