Solution

The correct option is B 57.5
Class interval Frequency Cumulative frequency
35458 8
455512 8+12=20
556520 20+20=40
657010 40+10=50
Total(N)=50
N=50
N2=25
Median lies in the class 5565

Now, median =l1+N2cff×h
where, l1=
lower limit of the median class

f= frequency of the median class

h= width (size) of the median class

cf= cumulative frequency of the class preceding the median class

Median =55+5022020×10=57.5

Hence, option B is correct.
