How should I find mean of these distributions and hence compare them ? I know the formula of mean but I am not able to apply it here.

Hi Amit,

Hint questions
What is the formula of the Mean?
When a column in histogram contains the value 33, what does it mean?

So sum all the salaries of all the people and divide by the number of people.

Ps I would say that 33 people have a salary between 20,000 and 30,000, so in average probably you can assume 25,000
