Answer:
The correct option is 2.
Step-by-step explanation:
According to the the center-of-gravity technique, the coordinates of the center-of-gravity location are

Where (
represent the coordinates and
is demand.
We have to find the Y-coordinate of the center-of-gravity location.
The sum of product of demand and corresponding y coordinates is

The sum of demanded units is

The Y-coordinate of the center-of-gravity location is




The Y-coordinate of the center-of-gravity location is 131. Therefore the correct option is 2.
