n = total frequency = 41

Median:= (41+1)th term

= 24 th term.

The 24 th term belongs to 400-450 class

Therefore Median class is 400-450.

L= lower limit of median class = 400

cf= cumulative frequency of preceding class=22

f = frequency of the median class = 6

c= length of the median class= (450

400)=50

M = L +

= 400 +

n+1 2 -cf f .C

41+1-22 2 x 50

=416.6666

=416.67

Therefore the median wage of the laborers is 416.67.
