The Histogram is as follows:

Steps:

i)Mark the upper corner of rectangle with maximum frequency as A and B.

ii)Mark the inner corner of adjacent rectangles to the above rectangle as C and D.

iii)Join AC and BD to intersect at J. From J, draw JM perpendicular to meet X-axis at M.

iv)The value of M on X-axis represents the mode.

Thus, Modal value = 46
