The maximum deposit outflow it can sustain without altering its balance sheet is: $50,000.
Let x represent the maximum deposit outflow
80,000-x
(200,000-x)×20%=80,000-x
40,000-.20x=80,000-x
x-.20x=80,000-40,000
0.80x=40,000
Divide both side by 0.80x
x=40,000/0.80
x=$50,000
Inconclusion the maximum deposit outflow it can sustain without altering its balance sheet is: $50,000.
