    Rt=1.332Ω (seen from V)

    E(820)=3.35v

    E(680)=3.35v

    E(960)=8.65v

    Equivalent resistance as seen from the battery:

    820||680 + 960 = 1332 ohms

    Loop current is E/R = 12.0 / 1332 = 9.011 mA

    Voltage across the 960 is 9.011 mA * 960 = 8.650 volts

    The remainder of the voltage is dropped across the 820 & 680, so

    12.0 - 8.650 = 3.350 volts across the 820 and the 680.
