I think they will be of the same values even if the plane that is being his is inclined up or down. They will his only a particular point with respect to horizontal distance (i.e. Range).

But the height of impact will change depending on the inclination. Agree. ?

How to work projectile?

Range means the horizontal distance covered by projectile.

The range of projectile on downward inclination is always less than the range of projectile in upward inclination plane in general (you can observe the same by throwing a ball in the air).

And the angle of projection of downward inclined projectile is always greater compared to upward one. Now as per condition of the statement given in question VELOCITY AND ANGLE OF PROJECTION MUST BE SAME IN BOTH UPWARD AND DOWNWARD INCLINATION. In the hypothetical condition in which angle of inclination is same the range of downward projectile need to be increased and it becomes greater than the range of the upward projectile.

I Guess the Range of the projectile depends on the angle of the upward and downward inclination.

If they have the same inclination angle, the range of the would be same. If there is the difference in their angle, then the range of the projectile will also be affected. What do you say?

Gravity helps to increase speed in downward direction.

Rang or projectile always depends on projection angle.

The max range got in 45°.

During upword prjectile accleration due to gravity act negetively and during its act (+). So valocity during downward direction is more.

I think it's equal because of 'same velocity'.

Upward force only one cosθ.
Downward forces are gravitational and sinθ.
