Salary                 No of persons         CF

5 - 10                   49                             49

10-15                  133                             133 + 49 = 182

15 - 20               63                               182 + 63 = 245

20 - 25              15                               245 + 15 = 260

25 - 30               6                               260  + 6 = 266

30 - 35              7                                 266 + 7 = 273

35 - 40              4                                273 + 4 = 277

40 - 45              2                               277 + 2 = 279

45 - 50              1                                279 + 1 = 280.


Now,

cumulative frequency = 49.

class size h = 5

lower limit = 10

f = 133.

n = 280/2 = 140


The median salary of the data = l +  \frac{ \frac{n}{2} - cf }{f} * h

                                                   = 10 +  \frac{140 - 49}{133} * 5

                                                   10 +  \frac{65}{19}

                                                    \frac{255}{19}

                                                   13.421.



Hope this helps!
