This can be easily solved using ratios:
\(\frac{Movie V}{Movie S}\) = \(\frac{2}{5}\) = 280

Therefore:
Movie V = \(\frac{2}{7}*280\) = 80
Movie S = \(\frac{5}{7}*280\) = 200

Answer is (D)

I solved as well. Must be a typo

D must be the correct answer. I have already edited

We need S so it is 5/7
5/7 of 280 is 200
