An ammeter can measure current up to $500 \mathrm{mA}$. There are $20$ equal divisions between $0$ and $100 \mathrm{A}$ marks on its scale. During an experiment to determine the equivalent resistance of the two resistors joined in parallel a student observes ammeter's pointer at $3$rd graduation mark after zero when the key is off and the pointer is at $17\mathrm{th}$ graduation mark after $200 \mathrm{mA}$ when the key is inserted into the plug. The correct value of the current flowing in the circuit is.
