The coil of a galvanometer has a resistance of 20.0 , and its meter deflects full scale

Question:

The coil of a galvanometer has a resistance of 20.0 Ω, and its meter deflects full scale when a current of 6.20 m A passes through it. To make the galvanometer into a no digital ammeter, a 24.8-mΩ shunt resistor is added to it. What is the maximum current that this ammeter can read?
