Answer:
d. Decrease by 0.045 minutes
Explanation:
<u>First Case</u>  
Time per unit for 250 batch size = (30 / 250) + 5 minutes 
Time per unit for 250 batch size = 5.12 minutes
<u>Second case</u>
Time per unit for 250 batch size = (30 / 400) + 5 minutes 
Time per unit for 250 batch size = 5.075 minutes
The decrease in manufacturing time = Old-time - New time  = 5.12 - 5.075  =  0.045 minutes
. So, it Decrease by 0.045 minutes
