Jamal wanted only to test the effect of the free fall and so he put his system in a vacuum to prevent air resistance. in free fall, will the crumpled or flat paper reach the ground first? the crumpled paper will reach the ground first. the flat paper will reach the ground first. both papers will reach the ground at the same time. it is hard to tell which would reach the ground first without experimentation.

When a paper is crumpled and then released the air drag on the paper is less while when we put the flat paper and released it from rest we can see that there is large surface area due to which it will have more air drag and hence it will reach later

So we can say that air friction or air drag depends on the surface area of object

More will be the surface area more is the drag force of air and hence less is the effective acceleration due to gravity

So when we drop the two objects in vacuum it will not have any friction force

and hence they both will have same gravity downwards

So in that case the two objects will reach the ground in same time

so its answer will be

Both papers will reach the ground at the same time.
