Answer:
240 units
Explanation:
We can find Optimal order quantity easily by Optimal order quantity formula using the fixed order quantity formula
Formula:: Optimal order quantity = [tex]\sqrt[2]{\frac{2CoD}{Ch} }[/tex]
Where
Co = Ordering cost per order
D = Annual demand
Ch = Holding cost per unit
Calculations
Lets put in the values
Optimal order quantity = [tex]\sqrt[2]{\frac{2CoD}{Ch} }[/tex]
Optimal order quantity = [tex]\sqrt[2]{\frac{2*6*12000}{2.5} }[/tex]
Optimal order quantity = 240 units
Note: There must have been a mistake in question options the answer is 240 and closest to 240 is option B
