Sorry I really don't understand this question. Please help.
Before we always use to add the percents and find the median at 50% how come not in this case? I mean to say, add 3+4+5+6+10+11 etc and when its 50% thats where median is.

Hi Radhika,
You're confusing this with a histogram chart. This chart has 7 ailments and each ailment has a percent. We know the total people in the population, so we can find the number of people who have each of the 7 ailments by multiplying the percentage by the total (400). The question is just asking for the median of these 7 values.
