What is the position of the box with banana?

Box P is kept four boxes above the box with mango where the box with orange is kept exactly in the middle between them. Only two boxes are kept between the box with orange and box O which is not kept at the topmost position. As many boxes kept above box O as below the box with Kiwi which is kept two boxes away from box N. Box Q with grapes is kept at an odd numbered position. Box M is kept immediately above the box with banana and two boxes below box L. The box with apple is kept immediately below the box with guava. Hence, cases 1 and 3 get eliminated. So final arrangement-
