Answer:

Since Median= 525

500-600 is median class

Frequency

20

Camulative frequancy

36+x+20= 56+x

Median= l+n/2-cf/f*h

Where l = lower limite of median class = 500

h= class - interval

100-0=100

n= fi = 100

cf= Camulative frequancy of the class before median class = 36+ x

f= frequancy of the median class =

20

I hope it help u
