Dear student,
 
Weekly wage No. of workers Adjusted frequency frequency
10-15 7 .....
15-20 10 ..... 10
20-25 27 ..... 27
25-30 15 ..... 15
30-40 12 6 6
40-60 12 3 3
60-80 8 2 2


Adjusted frequency is calculated for classes excluding class having minimum class interval.
So in given question, we will adjust frequency of classes from 30-40.

Adjusted frequency is calculated with formula : frequency * lowest class size​ / Class size of current class interval

Adjusted frequency of Class interval 30-40 = 12*5 / 10 = 6
Adjusted frequency of Class interval 40-60 = 12*5 / 20 = 3
Adjusted frequency of Class interval 60-80 = 8*5 / 20  = 2
