    Can we see your attempt first ??

    Tip - don't forget to connect the GND together

    I tried to solve it, but then I realized that Vout shouldn't be 100. I get confused.
    also I didn't know how to connect GND together

    Try again but this time with this redrawn circuit by me:

    Yes you can, but this circuit is tricky.

    I found that the sum of the branched currents is bigger than the primary current..why? how to solve it?

    Because in this case only one of the two diodes can conduct, and your job is to find out which one it is (based on circuit analysis).

    The positive terminal of the first battery is connected to the anode while the positive terminal of the second battery is connected to the cathode and because the batteries are equivalent, they canceled out each other. Is it right?
