For the given data with 120 observations, the less than ogive and more than ogive intersect at (42.5,60). The median of the data is :

A ) 60

B) 42.5

C) 120

D) 21.25

Given, the point of intersection of both less than and more than type ogive is (42.5, 60). Now, from this point draw a line perpendicular to x-axis and point at which it cuts the x-axis is the required median of the given data.

Thus, 42.5 is the required median.
