E) What is the average sales of cars in the last three months?

F) Find the ratio of sales in the first three months of the last three months.

Answer :

A) The actual sales was the same as the expected sales in the month of April. This is because the graph has only one point for the month of April which indicates that the value of the y-axis is the same for both the graphs.


B) The difference in actual and expected sales was maximum, i.e. 75, in the month of March.


Difference in January = 100 – 75 = 25


Difference in February = 125 – 100 = 25


Difference in March = 150 – 75 = 75


Difference in April = 125 – 125 = 0


Difference in May = 150 – 100 = 50


Difference in June = 150 – 125 = 25


C) The difference in actual and expected sales was the least, i.e. 0, in the month of April.


D) The sales of cars in Jan = 75


The sales of cars in Feb = 100


The sales of cars in March = 75


The total sales of cars in the three months = 75 + 100 + 75 = 250


E) The last three months are April, May and June.


The sales of cars in April = 125


The sales of cars in May = 100


The sales of cars in June = 150


The total sales of cars in the last 3 months = 125 + 100 + 150


= 375


Average = = = 125.


The average sales of cars in the last three months = 125.


F) The total sales in the first three months = 250


The total sales in the last three months = 375


Ratio = = =
