Below is given distribution of profit (in Rs.) per day of a shop in a certain town.
Calculate median profit of shops.

Profit (in Rs.)	500 - 1000	1000 - 1500	1500 - 2000	2000 - 2500	2500 - 3000	3000 - 3500	3500 - 4000
No. of shops	8	18	27	21	20	18	8

The relation between Mean, Median and Mode for a moderately skewed distribution is 

If the mode and mean of a moderately asymmetrical series are $$16$$  inches and  $$15.6$$  inches respectively, then most probable median is

If the mean of the distribution
$$\begin{matrix}
Variate & 6 & 7 & 1.9 & 9 & 10\\
Frequency & 1 & 2 & k & 3 & 4
\end{matrix}$$
is $$3.6$$
the value of $$ k$$ is equal

Marks obtained by 40 students of a class are shown as ,

Marks above	10	20	30	40	50	60	70	80
Number of students	40	34	26	$$f_{1}$$	6	$$f_{2}$$	1	0

the mean of the distribution estimated as 35.75, the respective values of $$f_{1}$$ and $$f_{2}$$ are, if $$f_{1}\::\:f_{2}\:=\:3:1$$

Find the median from the following table.

Marks scored	below 20	below 40	below 60	below 80	below 100
Number students	6	10	20	36	50

For a certain frequency distribution, the value of Mean is $$ 101 $$and Median is $$ 100$$. Find the value of Mode.

For a certain frequency distribution, the values of Mean and Mode are $$54.6$$ and $$54$$ respectively. Find the value of median.

Forty persons were examined for their Haemoglobin % in blood (in mg per 100 ml) and the results were grouped as below :
Determine modal value of Haemoglobin % in blood of persons.

Haemoglobins % (mg / 100ml)	13.1 - 14	14.1 - 15	15.1 - 16	16.1 - 17	17.1 - 18
No. of Persons	8	12	10	6	4

For a certain frequency distribution, the values of Median and Mode are $$95.75$$ and $$95.5$$ respectively. Find the Mean.
