Solving a problem in physics section 59 paragraph 95 el

95. In a network with a constant voltage U voltmeter shows the voltage U1 = 195 V, if it is connected in series with a resistor R1 and the voltage U2 = 190 V with its inclusion in series with a resistor R2 = 2R1. The resistance of the voltmeter r = 1,0 kW. To determine the resistance R1 and the voltage on the network.
