Here one of the two common faces (5) is in the same position, then according to the rule no (2) the remaining face with the 4 dots will be opposite to face with dots 2.
According to the rule (2) when 3 points are at the bottom then 4 points will be at the top.
The letters of the adjacent faces to the face with letter A, are B, F, C and E. Hence D is the letter of the face opposite to the face with letters (A).
From position I and III common face with % is in the same position. Hence according to rule (3) opposite is X.
In these 2 positions one common face with number 3, is in same position. Hence according to rule (3), 1 is opposite to 6 and 4 is opposite to 2. Therefore 5 is opposite to 3.
The colours adjacent to yellow are orange, blue, red and rose. Hence violet will be opposite to yellow.
According to the rule no. (3), common faces with number 2 are in same positions. Hence when the digit 5 is on the bottom then 1 will on the upper surface.
The adjacent faces to the face which 3 points have 2, 1, 4 and 6 points. Hence on the face which is opposite to the face which contains 3 points, there will be 5 points.
As the numbers 2, 3, 4 and 5 are adjacent to 6. Hence the number on the face opposite to 6 is 1.
According to the rule (2) when 'one' is at the top, then 5 will be at the bottom.
