Paper Cutting

In this chapter, we shall study the problems relating to the analysis of pattern that is formed when a folded piece of paper have been cut in a definite desing.

Problems on Paper Cutting: In this type of questions, a set of three figures showing the manner in which a piece of paper has been folded, is given. In each of the first two figures, a dotted line together with an arrow on it has been given. The dotted line is the reference line along which the paper has to be folded and the arrow indicates the direction of the fold. Thus, these two figures indicate the sequence in which the paper is folded. In the third figure there are marks showing the posiiton and the nature of the cut made in the folded sheet. The examinee has to select one of the figures from the set og four alternative figures which would most closely resemble the pattern when the paper is unfolded.

Remark: Evidently, the designs of the cut will appear on each one of the folds made in the paper.

Example : The following question consists of a set of three figures X,Y and Z showing a sequence of folding of a piece of paper . fig (Z) shows the manner in which the folded paper has been cut. These three figures are followed by four answer from which you have to choose a figure which would most closely resemble the unfolded form of fig . (Z).

A.     B.     C.     D. 

Answer : C

Explanation : See the figure carefully. When the paper is cut, the answer would be C.

Example : In the following question, you  are given a fig. (X) followed by four alternative figures (a), (b), (c) and (d) such that fig. (X) is embedded in one of them. Trace out the alternative figure which contains fig. (X) as its part

A.     B.     C.     D. 

Answer : B

Explanation : See the figure carefully. When the paper is cut, the answer would be C.
