Answer:
y - x = 16
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<u>Step(i)</u>:-
Given data set A is 9,5,y,2,x
<em>Mean of the Data set A </em>
<em> = </em><em></em>
<em> = </em><em></em>
<em>Given data set B is 8, x, 4, 1, 3</em>
<em>Mean of the Data set B </em>
=
<u><em>Step(ii):-</em></u>
<em>Mean of the Data set A = 2 X Mean of the Data set B </em>
<em> </em><em></em>
<em>On simplification , we get</em>
16 +x + y = 2( 16 +x)
16 + x + y = 32 + 2 x
16 + x + y - 32 - 2 x = 0
y - x -16 =0
y - x = 16
