# From the following distribution of monthly income of 60 people in a company. Draw less than and more than ogive curve and find the median on the graph.Find the median using the formula. Please can I get the answer quickly. Monthly income in thousand number of people 10-20 6 20-30 9 30-40 10 40-50 15 50-60 12 60-70 8 I tried this but I am getting median in graph differently than the value I am calculating using the formula.

 Item (X) Frequency (f) Cumulative Frequency (c.f) 10$-$20 6 6 20$-$30 9 15 30$-$40 10 25 40$-$50 15 40 50$-$60 12 52 60$-$70 8 60

Median class is given by the size of the ${\left(\frac{N}{2}\right)}^{\mathrm{th}}$ item, i.e. the ${\left(\frac{60}{2}\right)}^{\mathrm{th}}$ item, which is the 30th item.
This corresponds to the class interval 40$-$50, so this is the median class.
