$\text { given }:(N+1) V S D=N M S D$          $........(1)$

$\text { VSD }=\left(\frac{N}{N+1}\right) M S D$

given : $(N+1) \mathrm{VSD}=N \mathrm{MSD}$      $........(2)$

From ($1$) and ($2$)

$V \cdot C=(M S D)-\frac{N}{N+1}(M S D)$

$=M S D\left(1-\frac{N}{N+1}\right)=\frac{M S D}{N+1}$

$=\frac{0.01}{N+1}=\frac{1}{100(N+1)}$
