Solution
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)
