Answer:
Manufacturing efficiency ratio= 60%
Step-by-step explanation:
Manufacturing efficiency ratio measure the proportion of time it takes to perform value-added activities. This information is used to reduce time spent on non value-adding activities, thereby reducing cost and making production faster.
Using the formula
Manufacturing efficiency ratio= Value-added production time/ production cycle time
Value-added production time= Cycle time - non value-added manufacturing time
Value-added production time= 0.5-0.2= 0.3
Therefore
Manufacturing efficiency ratio= 0.3/0.5= 0.6
Manufacturing efficiency ratio= 60%
