Non Verbal Reasoning - Cubes and Dice - Discussion

The sheet of paper shown in the figure (X) given on the left hand side, in each problem, is folded to form a box. Choose from amongst the alternatives (1), (2), (3) and (4), the boxes that are similar to the box that will be formed.

2. 

Choose the box that is similar to the box formed from the given sheet of paper (X).

[A]. 1 and 4 only
[B]. 3 and 4 only
[C]. 1 and 2 only
[D]. 2 and 3 only

Answer: Option A

Explanation:

The fig. (X) is similar to the Form I. So, when the sheet shown in fig. (X) is folded to form a cube then one of the two half-shaded faces lies opposite to one of the blank faces and the other half-shaded face lies opposite to another blank face. The two remaining blank faces lie opposite to each other. Thus, both the cubes shown in figures (1).and (4) can be formed when the sheet shown in fig. (X) is folded. Also, though the cubes shown in figures (2) and (3) have faces that can appear adjacent to each other but the cube formed by folding the sheet in fig. (X) cannot be rotated to form either of the two. Hence, the cubes in figures (2) and (3) cannot be formed.

The black triangles are connected thru there pointed angles. See figure 4. then analyze the figure (x). Figure it out why they'll come to the answer option A.

Given answer is right.

Beacause option 2 and 3 triangle is not given in proper ways so given answer is true.
