$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\hline\begin{array}{||c||c||} \footnotesize \tt{ \underline{\underline{C.I}}}& \footnotesize \tt{\underline{\underline{C.F}}}\\\footnotesize \tt{Less \: than \: 10}&\footnotesize \tt{4}\\\footnotesize \tt{Less \: than \: 20}&\footnotesize \tt{12}\\\footnotesize \tt{Less \: than \: 30}&\footnotesize \tt{23}\\\footnotesize \tt{Less \: than \: 40}&\footnotesize \tt{38}\\\footnotesize \tt{Less \: than \: 50}&\footnotesize \tt{50}\\\footnotesize \tt{Less \: than \: 60}&\footnotesize \tt{56}\\\footnotesize \tt{\underline{\underline{Less \: than \: 70}}}&\footnotesize \tt{\underline{\underline{59}}}\end{array}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\footnotesize \tt \pink{ For \: More \: than \: ogive \: table}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\hline\begin{array}{||c||c||} \footnotesize \tt{ \underline{\underline{C.I}}}& \footnotesize \tt{\underline{\underline{C.F}}}\\\footnotesize \tt{More \: than \: 0}&\footnotesize \tt{59}\\\footnotesize \tt{More \: than \: 10}&\footnotesize \tt{55}\\\footnotesize \tt{More \: than \: 20}&\footnotesize \tt{47}\\\footnotesize \tt{More \: than \: 30}&\footnotesize \tt{36}\\\footnotesize \tt{More \: than \: 40}&\footnotesize \tt{21}\\\footnotesize \tt{More \: than \: 50}&\footnotesize \tt{9}\\\footnotesize \tt{\underline{\underline{More \: than \: 60}}}&\footnotesize \tt{\underline{\underline{3}}}\end{array}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\footnotesize \tt \pink{ Median \: is \: somewhat \: between \: 33 \: to \: 34 \: or \: 33.98}$

If you draw ogive in graph paper then you get the exact value of Median
