Draw a histogram for the given data, using a graph paper:
| Weekly Wages (in ₹) | No. of people |
|---|---|
| 3000 - 4000 | 4 |
| 4000 - 5000 | 9 |
| 5000 - 6000 | 18 |
| 6000 - 7000 | 6 |
| 7000 - 8000 | 7 |
| 8000 - 9000 | 2 |
| 9000 - 10000 | 4 |

Steps :
Take 1 cm along x-axis = 1000 rupees and 1 cm along y-axis = 2 (No. of people).
Construct rectangles corresponding to the given data.
In highest rectangle, draw two st. lines AD and BC from corners of the rectangles on either side of the highest rectangle to the opposite corners of the highest rectangle. Let P be the point of intersection of AD and BC.
Through P, draw a vertical line to meet the x-axis at M. The abscissa of the point M represents 5400.
Hence, mode = ₹ 5,400.
