Basic diode analysis problem

1. The problem statement, all variables and given/known data
Determine ##V_0## and ##I## for the network shown in attachment 1.

2. Relevant equations

3. The attempt at a solution
I can replace Si diode with a battery of emf of 0.7 V and Ge diode with that of 0.3 V.

If I take Path-1 (orange) in attachment 2, I get:
$$V_0=10-0.3=9.7 V$$
which is correct but if I take Path-2 (blue), I get:
$$V_0=10-0.7=9.3 V$$
Why do I get two different answers? :confused:

Any help is appreciated. Thanks!
