What is abscissa of the point of intersection of the "Less than type" and of the "More than type" cumulative frequency curve of a grouped data?

The abscissa of the point of intersection of the less-than type and of the more-than type cumulative frequency curves of a grouped data gives

Which central tendency is obtained by the abscissa of point of intersection of less than type and more than type ogives?

Convert the following distribution to more than type, cumulative frequency distribution :

The following distribution gives the daily income of 50 workers ofa factory: Convert the distribution to a less than type' cumulative frequency distribution and draw its ogive. Hence obtain the median of daily income.

The boiling point of ethyl alcohol should be less than that of

The following are the ages of 300 patients getting medical treatment in a hospital on a particular day: Form the "less than type" cumulative frequency distribution table.

The following distribution gives the daily income of 50 workers of a factory. Convert the distribution above to a less than type cumulative frequency distribution, and draw its ogive.

The following are the ages of 200 patients geting medical treatment in a hospital on a paticular day: Write the above distribution as "less than type' cumulative frequency distribution and also draw an ogive to find the median.

Change the following distribution to a more than type distribution and hence draw the more than type ogive for this distribution.

Given below is a frequency distribution table showing daily income of 100 workers of a factory : Convert this table to a cumulative frequency distribution table of 'more than type'.
