Class XA − Q & A

Someone answer my doubt with respect to thiss question paper : http://www.respaper.com/icse/410/4072-pdf.html

In question 8(c), the examiner's comments, point (ii) says that we should be "dropping a perpendicular" to the x axis to find the mode of a value. Does this mean that we should construct a perpendicular (using compass, scale and pencil)???

Please let me know your thoughts ASAP.

And, all the best for tomorrow!!!
