Potentiometer wire of length 1 m is connected in series with 490 Omega resistance and 2 V battery. If 0.2 mV/cm is the potential gradient, then resistance of the potentiameter wire is approximately

When a number is approximated to the nearest hundreds, the approximated value is 600 and absolute error is 24. Then the exact number is "_________" .
