The vehicle mass as a percentage of the total mass of the vehicle and the propellant can be found with the help of the mass ratio.
Initial Vehicle Mass of the rocket in percent is "25%".
The formula of the mass ratio is given as follows:
[tex]Mass\ Ratio=\frac{Vehicle\ Mass + Propellant\ Mass}{Vehicle\ Mass}\\\\[/tex] -------------- eqn (1)
The initial vehicle mass as a percentage of the total mass of the vehicle and the mass of the propellant, as follows:
[tex]Initial\ Vehicle\ Mass = \frac{Vehicle\ Mass}{Vehicle\ Mass+Propellat\ Mass}\\\\[/tex]
using eqn (1):
[tex]Initial \ Vehicle\ Mass = \frac{1}{Mass\ Ratio}\\\\Initial \ Vehicle\ Mass = \frac{1}{4}[/tex]
Initial Vehicle Mass = 0.25 = 25%
