Both the diodes are in on state and in this condition the voltage drop on them is $V_{d} \sim .7 V$ no matter which is the current...


Kind regards

I don't understand. the question is asking for the voltage with respect to the ground.:confused:

Let's start with point A.
There is a voltage source between ground and point A.
Its voltage is 25 V.
Therefore the voltage at point A is +25 V.

point B is 24.3v. because the voltage drop across the diode is 0.7v so 25-0.7v=24.3 v

but i don't know how to determine the voltage at point c.
