  I = 7; II = 1; III = 7; IV = 2; V = 6; VI = 0; VII = 2; VIII = 7

Step-by-step explanation:

For these, it usually works best to start with the region covered by all of the circles: V.

  V = A∩B∩C = 6

  V + II = A∩B = 7   ⇒   II = 1

  V + IV = A∩C = 8   ⇒   IV = 2

  V + VI = B∩C = 6   ⇒   VI = 0

  I + II = A∩C' = 8   ⇒   I = 7

  II + III + B∩C' = 8   ⇒   III = 7

  IV + V + VI + VII = C = 10   ⇒   VII = 2

  VIII = A'∩B'∩C' = 7

Putting these in order, we have ...

  I = 7; II = 1; III = 7; IV = 2; V = 6; VI = 0; VII = 2; VIII = 7
