A product whose EOQ is 40 units experiences a decrease in ordering cost from $90 per order to $22.5 per order. The revised EOQ is:
a) three times as large.
b) one-third as large.
c) nine times as large.
d) one-ninth as large.
e) half as large.
f) cannot be determined.
Ans) e ) Half as large
Working
We know EOQ = 2DK / h
D = Annual Demand
K = Ordering cost
h = holding cost per unit per unit of time
From question --
When K1 = $90
EOQ1 = 40 = 2DK1 / h
EOQ1 = 40 = (2D *90) / h
When K2 = $22.5
EOQ2 = 2DK2 / h
EOQ2= 2D * 22.5 / h
Now we need to find
(EOQ1 / EOQ2)
So that we will calculate EOQ2
(40 / EOQ2) =( (2D *90) / h ) / ( 2D * 22.5 / h )
Now D & h will reamin same and hence cancel out
So we have
(40 / EOQ2) = 90 / 22.5
(40 / EOQ2) =4
(40 / EOQ2) = 2
EOQ2 = 20
Now
(EOQ1 / EOQ2) = 40 / 20
EOQ2= 0.5 EOQ1
The revised EOQ is half of previous EOQ
