The average value of the emf of shaded part of the graph is 200 Volt.
Refer to the attached figure for the graph.
Average value of emf of the shaded part = 2 V₀/π = 0.636 V₀,
where V₀ is the alternating emf.
Value of alternating emf is 314 volt.
By substituting the value we get
Average value of emf = 0.636 × 314 = 200 volt
