Answer 1

Answer:

Average sales for November and December is 270 units.

Step-by-step explanation:

Average sales of saraswati motors from January to June = 150 units

Total sales from January to June = 150*6   (January to June is 6 months)

                                                                = 900 units

Average sales from July to October = 240 units

Total sales from July to October = 240*4  (July to October is 4 months)

                                                               = 960 units

Average sales for the year = 200 units

Total sales for the year = 200*12 (12 months in a year)

                                              = 2400 units

Let the total sales for November and December be X

Total sales in a year =

                                       X + 900 + 960 = 2400                 (equation 1)

                                       X = 540

Average sales for November and December = X/2

                                                                          =  270 units
