#### Data Interpretation

Direction: The bar graph given indicates the income of a firm. Study the graph and answer the questions given. 1. The average monthly income of the firm (in billion \$) is :

1. According to given bar graph , we have
Total income = 7 + 4 + 9 + 11 + 13 = \$ 44 billions
Number of months = 5

 Average income of the company = Total income Number of months

 Average income of the company = \$ 7 + 4 + 9 + 11 + 13 billion 5

##### Correct Option: C

According to given bar graph , we have
Total income = 7 + 4 + 9 + 11 + 13 = \$ 44 billions
Number of months = 5

 Average income of the company = Total income Number of months

 Average income of the company = \$ 7 + 4 + 9 + 11 + 13 billion 5

 Average income of the company = 44 = \$ 8.8 billion 5

1. The income in May is how many times to that of February?

The income in February = 4

1. During which month, the ratio of the income to that of the previous month is the largest?

1. According to given bar graph , we have
Income in February = \$ 4 billion
Income in March = \$ 9 billion
Required ratio = Income in March : Income in February

##### Correct Option: B

According to given bar graph , we have
Income in February = \$ 4 billion
Income in March = \$ 9 billion
Required ratio = Income in March : Income in February
∴ Required ratio = 9 : 4
