Let the amount after withdrawal be a, before withdrawal it was 125% of a or 1.25a
The decrease is 1.25a-a or 0.25a from 1.25a.
Therefore decrease % =100* 0.25a/1.25a=100/5=20%

let amount be 100
so
25% increase = 125
and amount which was withdrawn was 100-x
so
125*(100-x)= 100
x=496
% = 100/496 = 20%
IMO B
