Answer
Steps :
- Take 1 cm along x-axis = 10 units and 1 cm along y-axis = 2 units.
- Construct rectangles corresponding to the given data.
- In highest rectangle, draw two st. lines AC and BD 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 AC and BD.
- Through P, draw a vertical line to meet the x-axis at M. The abscissa of the point M represents 23.
Hence, the required mode = 23.
