A) 300
B) 350
C) 400
D) 450​

Answer 1

100+200+300/3=200

200+300+400/3=300

So Option A is correct I.e 300:

Answer 2

Given:

Demand in December=400

Demand in November=300

Demand in October=200

To find:

The 3-month moving average for the month of January

Solution:

The 3-month moving average for the month of January is 300. (Option A)

The 3-month moving average can be obtained by taking the sum of the demand for the last three months and dividing it by 3.

The last three months are December, November, and October.

So, the moving average for the month of January=(Demand in December+Demand in November+Demand in October)/3

=(400+300+200)/3

=900/3

=300

Therefore, the moving average for the month of January is 300.
