A figure (X) is said to be embedded in a figure (Y), if figure (Y) contains figure (X) as its part.   Type I: Identify the small part hidden in given figure. In such type of problems, a figure (X) is given, followed by four parts, such that one of them is embedded in figure (X). Candidate has to identify such part.   Type II: Identify the figure in which given part is hidden. In such type of problems, a figure (X) is given followed by four complex figures in such a way that figure (X) is embedded in one and only one of them. The candidate has to select such figure in which figure (X) is embedded.     EXAMPLE   more...

  Possible Combinations          

• How to make possible combinations/pairs of 1 - 1 objects from given m - n objects?
• If \[m=n,\]then number of possible (1 - 1) combinations of (m-n) objects are \[m\times m\].
• If \[m\times n\], then number of possible (1 - 1) combinations of (m-n) objects are \[m\times n\].

  Days and dates

• How to find the days required in question?
• We have to first naming what is today, yesterday and tomorrow.
• 8th day from today is again that day.

       Introduction   Pictograph is referred as the representation of data in picture form. In ancient time pictographs were only the method for writing the information. Numbers were also represented in picture form. Now a day pictographs are used for the analysis of data. In this chapter we will learn about the pictorial representation of data.            Pictograph and its Use Information about anything in the form of picture is called pictograph. There are different types of graphs which are used for the representation of data. These are bar graph, line graph, Venn diagram.                   Representation of Data by Pictograph

        Measurement of Capacity or Volume of Liquid   The capacity of a container is the maximum quantity of liquid that container cancontain. If the capacity of a container is 1 litre then it means, it can hold the volume1 litre of liquid inside it. The standard unit for the measurement of liquid is litre. The bigger volume of liquid is measured in litres and smaller volume in millilitre. One litre is equal to 1000 millilitres. Therefore, one millilitre is thousandths part ofone litre. Litre is denoted by small letter of English alphabet I and millilitre is expressed in ml.                 Addition of Two or More Volume of Liquid Addition by Conversion The following steps are used for the addition of the volume of liquid: Step 1:   Convert the volume into millilitres. more...

         Measurement of Mass   The standard unit for the measurement of mass is kilogram (kg) and gram (g). Mass of small object is measured in grams. 1 kilogram = 1000 grams. Therefore, one gram is thousandths part of one kilogram.                 Addition of Measured Masses Addition by Conversion Following steps are used for the addition of two or more masses: Step 1:   Convert kilograms into grams by multiplying thousand. Step 2:   Add them by simple addition. Step 3:   Express resulting numbers in gram.     The weights of three boys are 25 kg 400 grams, 30 kg 500 grams and 20 kg 234 grams. Find the total weight of the boys? (a) 76 kg 134 grams (b) 78 kg 150 grams (c) more...
