Answer:

9V

Explanation:

I'm not sure if this is correrct, but i assume you just do a loop in the path of D1 to the resistor to D3. Using kirchoff voltage law, they should sum up to 0. The forward voltage drop of each diode is already given so just sub those value i and solve for Vr (voltage drop over resistor).

10 - Vd1 - Vr - Vd3 = 0

10 - .3 - Vr - .7 = 0

Vr = 10 - .3 - .7 = 9V
