First arrange the 10 entries in ascending order.

Totally 10 entries

I quartile = 45

Median =61

III quartile = 91

--------------------------------------------------

Arrange the salaries in ascending order as follows:

65000 is repeated maximum number of times

Hence Mode = 65000

Range = Highest - Lowest

= 70000-25000 = 45000
