Expert Answer:

Ogives can be used to find the median of a grouped data. The median of grouped data can be obtained graphically by plotting the Ogives of the less than type and more than type and locate the point of intersection of both the Ogives.  The x-coordinate of the point of intersection of two Ogives gives the median of the grouped data.

Take the value of n/2 at y-axis and draw a perpendicular to the ogive. the x-coordinate the point of intersection is the median.

Hence, the median is 62(approximately).
