Can you flip V1 so as to make the circuit more legible, please? As drawn R1 could be either 25 or 125 ohms. Also it would be helpful if you could reproduce the entire question as set. Thank you. mike

Not enough information. We can ONLY express the voltage in terms of current and resistance. Since the TOTAL resistance is 200 ohms, then the applied voltage, Vtotal, is (current x 200) and the voltage drop at resistor R1 would be (0.625 x Vtotal), which is also equal to (current x 125), since this is a series circuit.
