The faces bearing the polygon and the arrow are opposite to each other. Therefore, these faces can not lie adjacent to each other, So that the cubes A, C and D cannot be formed. Hence, option (B) is the correct answer.


2. Choose from the alternatives, the boxes that will be formed when figure X is folded:

  A.  A, B, C & D
  B.  A & C only
  C.  A & B only
  D.  A, B & C only

The four triangular parts will combine to form a single face of the cube and the faces bearing the rectangular dot and the empty rectangle will both be adjacent to this face. In addition to it, the faces with black small rectangle and empty rectangle will lie opposite to each other. Hence, option (C) is the correct answer.


3. The figure X is given on the left hand side is folded in the form of box. Choose from the alternatives, the boxes that will be formed after being folded:

  A.  Only B
  B.  Only C
  C.  A & C only
  D.  Only D

When cube is formed, (ii) lies oppsite to (iv); (i) lies opposite (vi) and (v) lies opposite to (iii). Therefore, the pairs (ii & iv), (i & vi) and (v & iii) can't occur at adjacent faces. Hence, option (D) is the correct answer.


4. The figure X is given on the left hand side is folded in the form of box. Choose from the alternatives, the boxes that will be formed after being folded:

  A.  Only B
  B.  A & B only
  C.  Only D
  D.  Only C

When cube is formed , the tilde(~) face will lie opposite the face bearing the hash(#). So, the possibility of cubes (A) (D) is ruled out. Out of the cubes (B & C), the pattern in figure (X) shows that cube (B) will be formed. Hence, option (A) is the correct answer.


5. The figure X is given on the left hand side is folded in the form of box. Choose from the alternatives, the boxes that will be formed after being folded:

  A.  Only B
  B.  Only A
  C.  Only D
  D.  A & B only

Half shaded faces lie opposite to each other. The pattern in given figure (X) shows that on folding, each of the cubes A,B,C, & D will be formed. Hence, option (D) is the correct answer.


7. The figure X is given on the left hand side is folded in the form of box. Choose from the alternatives, the boxes that will be formed after being folded:

  A.  B & D only
  B.  C & D only
  C.  A & C only
  D.  B, C & D only
     
   
View Answer

The half shaded face and the completely shaded faces lie opposite to each other. Therefore, the cube (A) can't be formed. Further, the pattern in given figure (X) shows that out of the cubes B, C & D only the cubes B & D can be formed by folding given figure.Hence, option (A) is the correct answer.


8. The figure X is given on the left hand side is folded in the form of box. Choose from the alternatives, the boxes that will be formed after being folded:

  A.  Only D
  B.  C & D only
  C.  A & B only
  D.  B, C & D only

Faces bearing the 3 and 5 lie opposite to each other. Therefore the cubes A & B can't be formed. The pattern in given fig (X) shows that both the cubes C & D can be formed by folding given figure. Hence, option (B) is the correct answer.


9. The figure X is given on the left hand side is folded in the form of box. Choose from the alternatives, the boxes that will be formed after being folded:

  A.  Only A
  B.  B & C only
  C.  A & B only
  D.  Only D

Faces rectangle and circle are opposite to each other. So these faces can't be seen side by side. Similarly, black colored face is opposite to blank face side and grid face also opposite to blank face side. Therefore, black colored face with two blank face side can't be formed and grid faced with blank face side also can't be formed. Hence, option (C) is the correct answer.


10. The figure X is given on the left hand side is folded in the form of box. Choose from the alternatives, the boxes that will be formed after being folded:

  A.  B & C only
  B.  A,B & D only
  C.  A & B only
  D.  Only B
