Solution:

Here in the complex, potassium pentacyanonitrosylvandate (0), the number of potassium atoms per molecule and the coordination number of central metal ion are 5, 6 respectively as oxidation number of V in this complex is '0' thus the charge on pentacyanonitrosylvandate is -5. Thus formula of the complex is $K _{5}\left[ V ( CN )_{5} NO \right]$ .
