Step-by-Step Solution

To find the median wage, we identify the income value corresponding to the middle worker in the dataset.

1. Understand the Graph:

   • The X-axis represents Daily Income (in Rs.).

   • The Y-axis represents the Cumulative Number of Workers.

   • The graph shows a total of 50 workers.

2. Locate the Median Position:

   • For a set of 50 workers, the median position is the average of the 25th and 26th worker.

   • Mathematically, this is the position at (N / 2) = 50 / 2 = 25.

3. Find the Corresponding Income:

   • Look for the value 25 on the Y-axis (Number of Workers).

   • Trace horizontally from 25 to the graph line.

   • Trace vertically down from that point to the X-axis (Daily Income).

   • The intersection point on the X-axis falls between 120 and 140, specifically closer to 140. Given the curve's trajectory, the median value is approximately Rs. 138.
