Answer:
median =l+n/2-c.f/f×h
it is given that n=60
so,45+x+y=60
x+y=60-45=15
x+y=15
the median is 28.5 which lies between 20 and 30
median class=20_30
lower boundary of the median class=l=20
n/2=60/2=30
c.f=5+x,h=10
median=l+n/2-c.f/f×h
28.5=20+30-5-x/2×10
28.5=20+25-x/2
25-x/2=28.5-20=8.5
25-x=2×8.5
x=25-17=8
also from(1);x+y=15
8+y=15
y=7
x=8;y=7
