#### Data Interpretation

Direction: Study the following graph which shows income and expenditure of a company over the years and answer the questions. 1. The difference in profit (in Rs. crores) of the company during 2007 and 2008 is

1. From the given bar diagram , we see
Profit of company during 2007 = 45 – 40 = \$ 5 crore
Profit of company during 2008 = 60 – 50 = \$ 10 crore
Required Difference = Profit of company during 2008 - Profit of company during 2007

##### Correct Option: A

From the given bar diagram , we see
Profit of company during 2007 = 45 – 40 = \$ 5 crore
Profit of company during 2008 = 60 – 50 = \$ 10 crore
Required Difference = Profit of company during 2008 - Profit of company during 2007
Required Difference = 10 – 5 = \$ 5 crore

Direction: Study the graph and answer the questions. 1. In case of which soft drink was the average annual sale minimum during the period 1988-1993?

1. As per the given bar graph , we have
Total annual sales of Dew- drop = 10 + 15 + 25 + 15 + 30 + 25 = 120
Number of given years = 6

 Average annual sales of Dew- drop = Total annual sales of Dew- drop Number of given years

##### Correct Option: D

As per the given bar graph , we have
Total annual sales of Dew- drop = 10 + 15 + 25 + 15 + 30 + 25 = 120
Number of given years = 6

 Average annual sales of Dew- drop = Total annual sales of Dew- drop Number of given years

 Average annual sales of Dew- drop = 120 = 20 lakh bottles. 6

Average annual sales of Cool - sip = 20 lakh bottles.
Hence , correct answer is option D .

1. In which year sale of Dew-drop is maximum?

1. According to given bar graph , we have
Sales of Dew - drop in 1992 = 30 lakh bottles.

##### Correct Option: B

According to given bar graph , we have
Sales of Dew - drop in 1992 = 30 lakh bottles , which is maximum .Hence , required year is 1992 .

1. What was the approximate percent increase in sales of Cool-sip in 1990 over its sales in 1989?

1. As per the given bar graph , we have
Sales of cool – sip in 1989 = 6 lakh bottles
Sales of cool – sip in 1990 = 19 lakh bottles
Increase = 19 - 6 = 13 lakh bottles

 Required percent = Increase × 100 Sales of cool – sip in 1989

##### Correct Option: E

As per the given bar graph , we have
Sales of cool – sip in 1989 = 6 lakh bottles
Sales of cool – sip in 1990 = 19 lakh bottles
Increase = 19 - 6 = 13 lakh bottles

 Required percent = Increase × 100 Sales of cool – sip in 1989

 Required percent = 13 × 100 ≈ 217 6

1. What was the approximate percent drop in the sale of Pep-up in 1990 over its sale in 1989?

1. According to given bar graph , we have
Sales of Pep – up in year 1989 ⇒ 35 lakh bottles
Sales of Pep – up in year 1990 ⇒ 30 lakh bottles

 ∴ Required percent = Sales of Pep – up in year 1989 - Sales of Pep – up in year 1990 × 100 Sales of Pep – up in year 1989

##### Correct Option: B

According to given bar graph , we have
Sales of Pep – up in year 1989 ⇒ 35 lakh bottles
Sales of Pep – up in year 1990 ⇒ 30 lakh bottles

 ∴ Required percent = Sales of Pep – up in year 1989 - Sales of Pep – up in year 1990 × 100 Sales of Pep – up in year 1989

 Required percent = 35 - 30 × 100 35

 Required percent = 100 ≈ 14 % 7
