The question I'm asking about is Olymp 09
My attempt : 2.36 V
Vb1 / (R + r1 + r2) = 2 / 2.5 = 0.8 A
Vb2 / (R + r1 + r2) = 5 / 2.5 = 2 A
The reading of the voltmeter = the voltage across r1 + the voltage across r2 and R = (0.8)(2.2) + (2)(0.3)
= 2.36 V
I'm not sure of my answer, and even if it's correct I'm not completely convinced how is my solution is right.
