Least count is - 0.1mA
Least count of an instrument depicts the minimum value which can be measured and displayed.
Ammeter is the instrument which measures amount of current flowing through a conductor.
In the question, 50 divisions measure 500mA current. Hence, least count will be - 50/500 = 0.1
Thus, least count is 0.1 mA.
