Pictograph and Its Use

*       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   
  • A picture of a houserepresents one house.   
  • Pictures of two houserepresent 2 house.        
  • If one picture of a houserepresents 6 house then the pictures of 2 house will represent house. From the above representation of data we can say that a big quantity is represented by a symbol which is called pictorial representation of data.    
  represents 12 pencils. The symbolwill represent?     (a) 48   (b) 70   (c) 80   (d) All of these   (e) None of these   Answer (a) Expirations:  = 12 pencils therefore, four number of such pencils = 12 x 4 = 48 pencils.       *                Data Information about the things is called data. A surveyor conducts a survey regarding the T.V users in 4 areas A, B, C, D in a city and obtain the data: 50, 60, 45, 40. Row data is arranged in table as shown below:

Measurement of Capacity of Volume

*        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. Step 2:   Add them by simple addition method. Step 3:   Divide the resulting numbers of millilitres by 1000. Step 4:   Whole part of the quotient of division is in litres and decimal part is inmillilitres.   Volume of petrol is 1 L 600 ml and kerosene is 2 L 200 ml. The sum of both the capacity is? (a) 3 L 800 ml (b) 3 L 700 ml (c) 3 L 600 ml (d) None of these (e) All of these   Answer (a) Explanation 1 L 600 ml = 1000 ml + 600 ml = 1600 ml and 2 L 200 ml = 2000 ml + 200 ml= 2200 ml. The sum of both the capacity = 1600 ml + 2200 ml = 3800 ml bydividing thousand     *           Addition without Conversion The following steps are used for the addition of two volume: Step 1:Arrange the volume vertically. Step 2:Add by simple addition method from right. Step 3:If carry is generated then add carry to the next addition.      A container contains 3 L 234 ml of milk and another container contains 1 L 766 ml of milk. Find the total capacity of both the containers? (a) 31 (b) 51 (c) 11 (d) None of these (e) All of these   Answer (b) Explanation     *              Subtraction of Two Volume of Liquid Subtraction by Conversion The following steps are used for subtraction of volume of liquid: Step 1:   Convert the volume into millilitres. Step 2:   Subtract by simple subtraction method. Step 3:   Divide the resulting volume by 1000. Step 4:   Whole part of the resulting volume is in litres and decimal part is in millilitres.    What should be subtracted from 5 L 600 ml to get 3 L 700 ml? more...

Measurement of Mass

*         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) 70 kg 500 grams (d) None of these (e) All of these                      Answer (a) Explanation     Addition without Conversion The following steps are used for the addition of two or more masses: Step 1:   Arrange vertically kg under kg and grams under grams of all the given masses. Step 2:   Add them by simple addition method starting from right. Step 3:   If carry is generated then add generated carry to the next addition.       Add the following weights without conversion: 32 kg 930 grams and 22 kg grams?  (a) 55kg (b) 78kg                        (c) 70kg (d) None of these                   (e) All of these   Answer (a)           Explanations:      *               Subtraction of Measured Masses Subtraction by Conversion The following steps are used for finding the difference between two masses: Step 1:   Convert the masses into grams. Step 2:   Subtract the smaller mass from bigger mass. Step 3:   Express the resulting numbers in grams.       The weight of an unloaded truck is 1120 kg and its weight is increased by 2230 kg 560 grams on loading iron rods and cements. If the weight of iron rods is 1123 kg 300 grams then find the weight of cements in the loaded truck. (a) 1176 kg 176 grams (b) 1107 kg 260 grams (c) 1170 kg 500 grams (d) none of these (e) All of these   Answer (b) Explanations Weight of cements in the loaded truck = 1107 kg 260 grams.   Subtraction without Conversion The following steps are used for the subtraction of masses: Step 1:   Arrange vertically kg under kg and grams under grams of the givenmasses. Step 2:   Subtract smaller from bigger mass starting from right or grams. Step 3    Take borrow if required.     more...
