Question

find the marking frequency in the following table of uneq
ual 100 and median is 32​

Answer 1

class f cf

0-10 10 10

10-20 x 10+x

20-30 25 35+x

30-40 30 65+x

40-50 y 65+x+y

50-60 10 75+x+y

75+x+y

75+x+y=100

x+y=25

f=30,h=10,cf=35+x n/2=50

Median=l+( n/2-cf/f)×h

32=( 50-35-x/30)×10

32−30= 15-x/3

6=15−x

x=9

∴y=16
