Numerical -Shunt for given current, full scale deflection & P.D. of moving coil ammeter

Q.  A moving coil ammeter requires a potential difference of 0.4V across it for full scale deflection. It has fixed shunt resistance of 0.01 ohm with a coil circuit resistance of R = 1kohm. The value of shunt required to give full scale deflection when the total current is 10A is equal to
