| Daily Income (in ₹) | Number of Workers (f) |
|---|---|
| 200 - 300 | 6 |
| 300 - 400 | 10 |
| 400 - 500 | 14 |
| 500 - 600 | 16 |
| 600 - 700 | 10 |
| 700 - 800 | 4 |
Use graph paper to answer this question.
Take 2 cm = ₹ 100 along one axis and 2 cm = 2 workers along the other axis. Draw a histogram and hence find the mode of the given distribution.

Answer
Steps of construction :
Draw a histogram of the given distribution.
Inside the highest rectangle, which represents the maximum frequency (or modal class), draw two lines AC and BD diagonally from the upper corners C and D of adjacent rectangles.
Through the point K (the point of intersection of diagonals AC and BD), draw KL perpendicular to the horizontal axis.
The value of point L on the horizontal axis represents the value of mode.
From graph,
L = ₹ 525
Hence, required mode = ₹ 525.
