उत्तर

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 = `"Total production"/"Number of months"`

= `(600 + 800 + 700 + 1100 + 900 + 500)/6`

= `4600/6`

= 767 bikes  ...(approx)
