a. 801.25 units
b. 83.33 units
c. 640 units
d. 798.75 units
e. 1000 units

Answer 1

Answer:

Demand in January will be 640 units

So option (C) will be the correct option

Explanation:

We have given average demand for a particular product is 800 units

And seasonal index = 0.8

We have to find the demand in a particular session , that is in January

We know that seasonal index is given by

$Seasonal\ index=\frac{demand\ in\ a\ particular\ season}{average\ demand}$

So $0.8=\frac{demand\ in\ January}{800}$

So demand in January = 640

So option (c) will be the correct option
