Question

Observe the given bar graph carefully and answer the questions that follow.

1. What information does the bar graph depict?
2. How many motor bikes were produced in the first three months?
3. Calculate the increase in production in May over the production in January.
4. In which month the production was minimum and what was it?
5. Calculate the average (mean) production of bikes in 6 months.

Answer 1

a. The given bar graph shows the production of motorbikes by XYZ automobiles Ltd from January to June.

b. Total number of motorbikes produced in first three months = Motor bikes produced in January + Motorbikes produced in February + Motorbikes produced in March

= 600 + 800 + 700

= 2100

c. Increase in production in May over the production in January

= Production in May – Production in January

= 900 – 600

= 300

d. By observing the graph, we can say that the production was minimum in the month of June, i.e. 500.

e. Average production = ${\displaystyle \frac{\text{Total production}}{\text{Number of months}}}$

= ${\displaystyle \frac{600+800+700+110+900+500}{6}}$

= ${\displaystyle \frac{4600}{6}}$

= 767 bikes .....(approx).
