The question you have asked depends on some conditions.
If the above experiment is done in Vaccum or free space then both the objects will reach the same time. The reason is that in Vaccum or in free space they only experiencing the acceleration due to the gravity.
Also from equation of motion,
s = ut + 1/2 at^2 it can be concluded that the reaching of ground of both objects is independent of their respective masses.
However the above statement is only for the Vaccum.
If you done the experiment in normal conditions you will get different results.
The body with the heavier mass will reach on the ground generally first as by taking the Air resistance(Viscosity) and other factors in account.
From above we can conclude one thing that the experiment will have different results if you change the medium.
Hope you get your answer.
