Question 1144214
.
<pre>

We are given non-zero values A and B, as well as the non-zero values of A', B' such that


    A' = 0.75*A  and  A*B = A'*B'.


Then 


    A*B = (0.75*A)*B',


hence  (canceling A in both sides)


    B = 0.75*B'


and


    B' = {{{B/0.75}}} = {{{(1/0.75)*B}}} = {{{(1/((3/4)))*B}}} = {{{(4/3)*B}}} = 1.333333*B.


<U>ANSWER</U>.  B increased by  {{{33}}}{{{1/3}}} percents.
