Given alongside is a bar graph. Look at it carefully and answer the following questions: Which class has the highest percentage of students present?

In a bar diagram or bar graph, bars of uniform width are drawn horizontally or vertically with equal spacing between them. The height of the bar represents the numerical value of the data. The longest bar represents the maximum number (frequency) and the shortest bar represents the minimum number (frequency) corresponding to the given item. Bar graph helps us to compare the values of given data quickly. Given graph is, It represents the percentage of students present in class VI to X . In the given bar graph, we have, classes on x - axis and the percentage of students present on y - axis. We can see that VI has the highest percentage of students present, the bar of that class is the tallest.

Given alongside is a bar graph. Look at it carefully and answer the following questions: In which class are the students most irregular? Should you be regular or irregular in your school?

In a bar diagram or bar graph, bars of uniform width are drawn horizontally or vertically with equal spacing between them. The height of the bar represents the numerical value of the data. The longest bar represents the maximum number (frequency) and the shortest bar represents the minimum number (frequency) corresponding to the given item. Bar graph helps us to compare the values of given data quickly. Given bar graph is: It represents the percentage of students present in the classes VI to X . From the given bar graph, it is clear that students of class X are the most irregular as the bar of that class is the smallest in height. We should be regular to the school.

A pictograph given below shows the number of visitors in Red Fort during a week: Find the total number of visitors during the week?

Given is a pictograph which shows the number of visitors in Red Fort during a week. Also, 1 , 000 visitors is represented using image of the face. To find the total visitors, add the faces from Monday to Saturday and then multiply the sum with 1000 . Total faces = Monday + Tuesday + Wednesday + Thursday + Friday + Saturday = 10 + 7 + 9 + 4 + 6 + 8 = 44 Thus, the total number of visitors during the week is 44 × 1000 = 44 , 000 .

A pictograph given below shows the number of visitors in Red Fort during a week: On which day was the number of visitors minimum?

Given is a pictograph, that shows the number of visitors in Red Fort during a week. The number of visitors on Monday = 10 × 1 , 000 = 10 , 000 The number of visitors on Tuesday = 7 × 1 , 000 = 7 , 000 The number of visitors on Wednesday = 9 × 1 , 000 = 9 , 000 The number of visitors on Thursday = 4 × 1 , 000 = 4 , 000 The number of visitors on Friday = 6 × 1 , 000 = 6 , 000 The number of visitors on Saturday = 8 × 1 , 000 = 8 , 000 Hence, the number of visitors was minimum on Thursday.

A pictograph given below shows the number of visitors in Red Fort during a week: Find the number of visitors on Friday. Should we litter things around while visiting an old monument?

Given is a pictograph, which shows the number of visitors in Red Fort during a week. Now, we should find the number of visitors on Friday. From the pictograph, Thus, number of visitors on Friday is = 6 × 1 , 000 = 6 , 000 The number of visitors on Monday = 10 × 1 , 000 = 10 , 000 The number of visitors on Tuesday = 7 × 1 , 000 = 7 , 000 The number of visitors on Wednesday = 9 × 1 , 000 = 9 , 000 The number of visitors on Thursday = 4 × 1 , 000 = 4 , 000 The number of visitors on Friday = 6 × 1 , 000 = 6 , 000 The number of visitors on Saturday = 8 × 1 , 000 = 8 , 000 Hence, the number of visitors on Friday is 6 , 000 . We should not litter things around while visiting an old monument.
