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
