Please see the work below.

Work Step by Step

We know that $P=Fv$ This can be rearranged as: $F=\frac{P}{v}$............eq(1) Weight of single person$=67Kg\times 9.8=656.6N$ Weight of n persons$=n\times 656.6N$ We plug in the known values in eq(1) to obtain: $n\times 656.6N=\frac{330\times 10^3}{16.83}$ This simplifies to: $n=30$ persons
