CI                    Fi               CF

0-100               2               2

100-200           5               7

200-300          x                7+x

300-400          12              19+x

400-500           17              36+x

500-600           20            56+x

600-700            y              56+x+y

700-800            9              65+x+y

800-900            7              72+x+y

900-1000           4              76+x+y

N/2 = 100/2 = 50

76+x+y =100

x+y=24.........(1)

Now put the value of finding the Median

                          Median= l+(n/2-CF)/f *h

                         525  = 500 +(50-36+x)/20*100

                        525-500 =(14+x)/20*100

                                25  =  (14+x)5

                                25/5= 14+x

                                  14-5=x           x=9

       Now put the value of x in (1),

                   24-x=y

                     24-9=y

                                  y=15

Therefore, value of x=9 and y=15.
