Study the following information carefully and answer the question given below.

Seven boxes A, B, C, D, E, F and G are placed one above the other. All are of different colours, viz. Yellow, Brown, Pink, Green, Red, Black and Blue, but not necessarily in the same order. Each box contains a different item, viz. Balls, Pencils, Chocolate, Juice, Berry, Toys and Bottles, but not necessarily in the same order.

Box A is placed three places above the brown-coloured box. More than three boxes are placed between box B and the yellow-coloured box. The blue-coloured box is placed below the box that contains Bottles and above the box that contains Balls. The box that contains Chocolate is placed just above box B. Two boxes are placed between box B and box E, which contains Juice. Box C is of red colour and is placed two places above box E. The brown-coloured box contains Pencils, but it is not box B. Box F is placed above the yellow-coloured box. The black-coloured box contains Toys and is placed below box D. The green-coloured box contains Berry.

If box A and box E are interchanged with each other, then how many boxes are placed above box A?
