6 Answers ID : in-6-data-handling [6] (1) kg. If we look at the given chart carefully, we notice that the production of onions, carrots, tomatoes in a farm is 25%, 25%, 50%, respectively. The production of carrots is 3750 kg, which is 25% of a farm. Or, we can say that 25% production of a farm = 3750 kg % production of a farm = 25 25% production of a farm = = 3750 kg, and 50% production of a farm = = 7500 kg. Since the production of carrots and tomatoes is 25% and 50% of a farm, respectively. Therefore, the combined production of carrots and tomatoes = 25% production of a farm + 50% production of a farm = = kg

7 ID : in-6-data-handling [7] (2) Number on the Dice Tally Numbers Number of appearances (a) 3 (b) 6 Let us first make a table by counting the numbers as following: Number on the Dice Tally Numbers Number of appearances (a) If we look at the data table, we notice that '3' appeared maximum number of times. Therefore, the number that appeared maximum number of times is 3. (b) If we look at the data table, we notice that '6' appeared minimum number of times. Therefore, the number that appeared minimum number of times is 6.

8 (3) (a) 6 (b) 4 (c) 280 ID : in-6-data-handling [8] If we look at the pictograph, we will notice that each = 10 clocks. Therefore, Number of clocks manufactured by the factory 1 = 4 10 = 40 clocks Number of clocks manufactured by the factory 2 = 5 10 = 50 clocks Number of clocks manufactured by the factory 3 = 3 10 = 30 clocks Number of clocks manufactured by the factory 4 = 2 10 = 20 clocks Number of clocks manufactured by the factory 5 = 4 10 = 40 clocks Number of clocks manufactured by the factory 6 = = 100 clocks. (a) Therefore, the factory which manufactures the maximum number of clocks: 6. (b) The factory which manufactures the minimum number of clocks: 4. (c) Total number of clocks manufactured by all the factories in a day = = 280 clocks (4) (a) 3 (b) 7 (c) 37 (a) It is clear from the given pictograph that there are 10 bananas in the bag 3. This is the maximum number of bananas in all the bags. Therefore, we can say that the bag 3 has the maximum number of bananas. (b) It is clear from the given pictograph that there are 2 bananas in the bag 7. This is the minimum number of bananas in all the bags. Therefore, we can say that the bag 7 has the minimum number of bananas. (c) Total number of bananas in all the bags = Sum of the bananas in all the 7 bags = = 37 bananas

9 (5) (a) Wednesday (b) Thursday, Saturday and Sunday (c) kg ID : in-6-data-handling [9] In the given bar chart, length of the bar indicates the consumption of wheat on a given day. Day when the consumption of wheat is maximum = The day on which bar is longest. We can see that the bar is longest on Wednesday. Therefore, consumption of wheat is maximum on Wednesday. Day when the consumption of wheat is minimum = The day on which bar is shortest. We can see that bar is shortest on Thursday, Saturday and Sunday. Therefore, consumption of wheat is minimum on Thursday, Saturday and Sunday. Step 4 If we look at the bar chart, we will notice that at x-axis 1 unit = 1000 kg The length of bar on Friday = 60 Therefore, the consumption of wheat on Friday = = kg (6) 9750 pieces. If we look at the given chart carefully, we notice that the production of shirts, ties, gloves in a garment factory is 50%, 25%, 25%, respectively. According to the question, the production of shirts is pieces, which is 50% of the garment factory. or we can say that 50% production of the garment factory = pieces % production of a garment factory = 50 25% production of the garment factory = = 9750 pieces. Since, the production of gloves is 25% of the farm and 25% production of the garment factory is 9750 pieces, the production of gloves will be 9750 pieces.

10 (7) Football ID : in-6-data-handling [10] If you look at the circle chart carefully, you will notice that the sport which has most survey in circle chart is Football. The sport which has most survey in circle chart, is the most liked sport among students in Vadodara, therefore the most liked sport among students in Vadodara is Football.

11 ID : in-6-data-handling [11] (8) Marks Tally Marks Number of students (a) 15 (b) 9 To count the marks obtained by the students, look at the following tally table: Marks Tally Marks Number of students Number of student who scored more than 6 marks Or, the number of students who scored marks 7, 8, 9 = = 15 students Number of student who scored marks equal or less than 3 Or, the number of students who scored marks 2, 3 = = 9 students

12 (9) (a) 2 and 3 (b) 1 and 4 (c) 320 ID : in-6-data-handling [12] Class Number of girl students ( = 10 girls) If we look at the pictograph carefully, we will notice that: (a) Class 2 and 3 has the maximum number of the girls. (b) Class 1 and 4 has the minimum number of the girls. (c) Total number of in the school = The sum of the of each class = = 32. Step 4 Since, = 10 girls. Therefore, the total number of girls in the school = = 320. (10) (a) 1986 (b) 1988 The following table shows the amount of sugar purchased (in tons) by the government from 1986 to Year Amount of sugar purchased (in tons) If we look at the table, we will notice that (a) In 1986, the government purchased the maximum amount of sugar. (b) In 1988, the government purchased the minimum amount of sugar.

13 (11) School bus ID : in-6-data-handling [13] If we look at the circle chart carefully, we notice that the least covered area in the circle chart is School bus. We know that the least covered area in the circle chart implies the least preferred transport for coming to school. Therefore, the least preferred transport for coming to school is School bus.

14 (12) (a) Geography (b) History and English (c) 80 ID : in-6-data-handling [14] If we look at the graph, we will notice that x-axis and y-axis show the marks and subjects of Aditya in class 6 examinations, respectively. (a) Since the graph shows the maximum value against the subject Geography, the subject in which Aditya obtained the maximum marks is Geography. (b) Since the graph shows the minimum value against the subjects History and English, the subjects in which Aditya obtained the least marks are History and English. Step 4 (c) The graph shows 50 against Science. Thus, the marks obtained by Aditya in Science are 50. The graph shows 30 against Social Studies. Thus, the marks obtained by Aditya in Social Studies are 30. Step 5 The combined score of Aditya in Science and Social Studies = = 80.

15 (13) Cycle ID : in-6-data-handling [15] If we look at the circle chart carefully, we notice that the means of transport which has the least area covered in the circle chart is 'Cycle'. We know that the least covered area in the circle chart implies the least preferred means of transport. Therefore, the least preferred means of transport for coming to school is Cycle. (14) b. 40 Let us draw a table representing the fruits' name and quantity with the help of the given bar chart. Fruit's name Fruit's quantity Banana 60 Mango 30 Papaya 50 Pomegranate 10 Guava 20 Plum 70 Peach 40 From the table, we notice that the number of papayas in the shop = 50 The number of pomegranates in the shop = 10 Now, the difference between the number of papayas and pomegranates in the shop = = 40 Hence, we can say that there are 40 more papayas than pomegranates.

16 (15) a. pomegranates ID : in-6-data-handling [16] Let us draw a table to represent the fruits' name and quantity with the help of the bar chart. Fruit's name Fruit's quantity Banana 30 Pomegranate 50 Pineapple 40 Plum 20 Peach 70 From the above table, we notice that the number of pomegranates in the shop = 50 The number of pineapples in the shop = 40 Now, the difference between the number of pomegranates and pineapples in the shop = = 10 Therefore, we can say that there are 10 more pomegranates than pineapples.
