Answer
Steps of construction of histogram :
Since the scale on x-axis starts at 850, a kink is shown near the origin on x-axis to indicate that the graph is drawn to scale beginning at 850.
Take 2 cm along x-axis = 100 rupees.
Take 1 cm along y-axis = 10 workers.
Construct rectangles corresponding to the above continuous frequency distribution table.
The required histogram is shown in the adjoining figure.
