Question

i want the answer in pictures​

Answer 1

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
