Answer:
166.25 hours
Step-by-step explanation:
It take 25 hours if the production is going at 100% capacity, but the production is only going at 67%, therefore, 33% of the capacity is under utilized. It takes 8.25 more hours to finish the unit since the capacity is only at 67%. Finally, it takes 25+8.25 hours to finish a single product, hence taking 166.25 hours for 5 units.
We do this like this:
--> 25 ------ 100
--> X ------ 33
--> 33*25 = 100*X
--> 825/100
--> X=8.25
Hope this clears everything. Thankyou.
