Solution

Observing the graph carefully, we conclude that

a. In April, the actual sales was same as the expected sales.

b. In March, the difference in actual and expected sales was the maximum.

c. In April, the difference in actual and expected sales was the least.

d. The total sales of cars in the months January, February and March was (75 + 100 + 75) i.e. 250.

e. The average sales of cars in the last three months is 125 i.e. 125 + 100 + 150/3 = 125.

f. The number of sales of car in the first three months = 250 and the number of sales of car in the last three months = 375

The required ratio is 250 : 375 i.e. 2 : 3.
