(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 $20$.

Height (in $cm$)	Frequency	Cumulative frequency
$150-155$	$12$	$a$
$155-160$	$b$	$25$
$160-165$	$10$	$c$
$165-170$	$d$	$43$
$170-175$	$e$	$48$
$175-180$	$2$	$f$
Total	$50$	-

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