10th Class

TYPE-I Alpha-Numeric lest A sequence made up of three different systems namely Alphabet or Letters (A, B, C, D,….Z,) Numeric or Digits (0, 1, 2, 3,..,9) and symbols is called Alpha-Numeric Sequence   TYPE-II Number Test In this type of problems generally a number sequence is given. A candidate is required to apply some rule(s) on the sequence.   TYPE-III Ranking Test In this type of problems, usually a rank puzzle is given. It may be in the form of comparison or sizes/ heights, weights,, strengths/ ages etc. among the objects/persons.   TYPE-IV Time Sequence Test In this type of problems, a time puzzle is given. One is required to decipher it. 1 ordinary year = 365 days 1 leap year = 366 days 1 century = 100 years Number of days in February in a non-leap year = 28. Number of days in February in a leap year = more...

  This chapter contains only mathematical operations but in different manner. The main key of solving problem in this chapter is BODMAS rule to which you are already familiar This chapter consists of the following two types of problems.   1.            Direct Substitution To solve such type of problems, substitute the symbols \[+,-,\text{ }\times ,\div \] etc., for the given letters or symbol as per the question and simplify the statement using BODMAS rule,   2.            Interchange of Numbers and Signs To solve such type of problems, interchange the numbers with signs as per the given questions and more...

  INSERTING THE MISSING CHARACTER In such type of problems, a figure/design/table or a group of figures is given. This figure consists of some numbers or letters or both following a certain pattern. In fact, one space for a number letter is left blank which is to be filled up. In order to fill in the blank space a student is required to decipher the pattern.   Trick: To decipher a pattern, use various mathematical operations viz, addition, subtraction, multiplication, division and their combinations.     EXAMPLE     1.         Select the number which will replace the mark'?' in pattern given below.   (a) 64                            (b) 100              (c) 81               more...

  The chapter Series deals us with the group of figures which forms a series by using a certain rule. Obeying this rule, the figures depicts a change step by step. This chapter consists of the following types of problems and to solve each type, a student first needs to identify the rule or pattern. A student may come across two types of series: 1. To choose a figure which would continue the given series of figures. 2. To choose a missing figure that is capable to establish a series.     EXAMPLE     1.         Find the figure from the options which will continue the series established by the Problem figures.             more...

ANALOGY In such type of problems, generally we are given two pairs of figures, out of them one figure is missing. This missing figure has to be identified from amongst the four options. The figures in the complete pairs have a relationship between themselves. The same relationship has to be established by choosing an appropriate figure to complete the incomplete pair.             The complete pair may have any of the following relationships:                           1.     One is the mirror/water image of the other one. 2.     One is the reduced/enlarged size of the other one. 3.     One is rotated through an angle to form the other one. 4.     more...

This chapter is based upon the counting of various geometrical figures in a given complex figure.     EXAMPLE     1.         Count the number of triangles in the given figure.   (a) 14                            (b) 15              (c) 16                            (d) 17   Explanation (c): Let us label the given figure as shown in the adjoining figure.   Triangles made up of one segment: ANH, AOH, LBN, MCO, BDI, CEI, IDJ, IEJ. These are 8 triangles. Triangles made up of two segments: ABI, ACI, IFK, IGK, ANO, IDE. These are 6 triangles. No triangles made up more...

  Every human being often comes across mirror or water image of himself/herself or other objects. So, mirror and water images are common incidents in human life and so everybody is familiar with them. This chapter leads us mirror and water images of letters, words, numerals, figures, designs etc. Note: (i)     In the problems on mirror images, if not mentioned the mirror is assumed to be placed at vertical right of the object. (ii)    In the problems on water images, if not mentioned the water level is assumed to be the situated horizontally just below the object. (iii)   If the mirror is placed horizontally just below the object, then its mirror image and water image becomes identical. more...

SPOTTING OUT EMBEDDED FIGURE In such type of problems, a figure (X) is followed by four option figures. A student is required to observe that the given figure (X) is exactly embedded in which of the option figures. Remember that the given figure (X), may be embedded after rotating it.   COMPLETSON OF INCOMPLETE PATTERN In such type of problems, a regular design is provided of which usually a quarter is missing and so it is left blank or a question mark is placed in it. A student is required to study the pattern and then select an appropriate segment from the given options which completes the pattern.   EXAMPLE   1.         Choose one figure from among the four option figures in which the given Fig. (X), is exactly embedded.                         more...

 In such type of problems, a or  matrix is given. All the cells except one of the matrix contain a figure each. Thus a figure is missing. Figures in each row or column follow a common rule. In order to fill in the blank cell by taking a figure amongst the given alternatives, a candidate is required to identify the rule.     EXAMPLE    Select a figure from the options to complete the given matrix. (a)                  (b) more...

This chapter carries two types of problems one of folding a transparent sheet carrying a design and other one of folding a paper, then cutting it and then unfolding it.   PAPER FOLDING In such type of problems, there is a design drawn on any one side of a transparent sheet. This sheet is to be folded along a dotted line marked on it. A candidate is required to identify which pattern would be visualized after folding the sheet along the dotted line.   PAPER CUTTING In such type of problems, a sheet of paper is folded twice or thrice or more as per the shown directions. Then some cuts/punches are made on it. Then the sheet is unfolded. Now the sheet shows a pattern. A candidate is more...
