Answer 1

From class limit 0 to 10, the frequency is 6. But, after that, from class limit 0 to 20, the frequency is 15. So, as you know that for calculating median, the class limit should be continuous, we have to calculate the frequency of class limit 10 to 20.

Given, Frequency of Class limit 0-10 = 6

Frequency of class limit 0-20 = Frequency of class limit 0-10 + Frequency of class limit 10-20

Putting the values of the frequencies, we get :

15 = 6 + Frequency of class limit 10-20

=> Frequency of class limit 10-20 = 15-6 = 9

Similar step should be followed and continued.
