Question

plz answer it step by step plz ​

Answer 1

Step-by-step explanation:By making the C.F. = 5 , 5+x ,25+x , 40+x ,40+x+y , 45+x+y

F= 20 N=60

L= 20

H= 10

CF= 5+X

MEDIAN = 28.5

acc. to formula of MEDIAN =

median= L+(n/2-cf)×H

---------

F.

28.5= 20+(60/2-(5+x)) ×10

--------------

20.

28.5-20 =(30-5-x)

---------

2.

8.5=25-x.

--------

2.

8.5×2= 25-x.

17.0 -25 = -x.

-8 = -x.

X= 8.

45+x+y =60. ( Check last Cf from

the row) its 45+x+y

Put the value of X=

45+8+y=60

53+y=60

Y=60-53

Y=7
