Calculate the mean of the following series. Weekly wages (Rs.) Below 20 20-50 50-90 90-140 Above 140 No. of workers 10 20 40 15 15 Now in the above example the magnitude of the second class interval is 30, of the third class-interval 40, of the fourth interval 50 which means that each time the magnitude is rising by 10. On this assumption the magnitude of the first class would be 20 and of the last class 60. The class-intervals would then be as follows. 0-20, 20-50, 50-90, 90-140, 140-200 With these class-intervals mean would be calculated as follows :
