(A) The median of a frequency distribution can be determined graphically by drawing both the 'less than' type and 'more than' type Ogives.The point of intersection of these two Ogives provides the median value.The $x$-coordinate of this intersection point represents the median of the data,while the $y$-coordinate represents the cumulative frequency corresponding to the median.Given that the intersection point is $(20, 25)$,the $x$-coordinate is $20$.Therefore,the median of the data is $20$.

Class	$10-20$	$20-30$	$30-40$	$40-50$	$50-60$
Frequency	$12$	$16$	$8$	$6$	$8$

Class	$0-10$	$10-20$	$20-30$	$30-40$	$40-50$	$50-60$	$60-70$	$70-80$
Frequency	$2$	$6$	$8$	$16$	$20$	$18$	$16$	$14$

The two types of Ogives drawn for a frequency distribution intersect at point $(20, 25)$. Then,the median of the data is .......
