Read the given bar graph and answer the following : Name the person with the greatest number of heart beats per minute.

Given graph is: A Bar Graph (also called Bar Chart) is a graphical display of data using bars of different heights. We can collect the data or information from bar graph by seeing vertical and horizontal side in heart beats (in minutes) by persons. Shankar has 45 heartbeats per minute. Manish has 70 heartbeats per minute. Raman has 50 heartbeats per minute. Shambhu has 60 heartbeats per minute. Guddu has 55 heartbeats per minute. Thus, Manish has the greatest number of heartbeats per minute.

Read the given bar graph and answer the following : Name the person with the least number of heart beats per minute.

Given graph is: A Bar Graph (also called Bar Chart) is a graphical display of data using bars of different heights. We can collect the data or information from bar graph by seeing vertical and horizontal side in heart beats (in minutes) by persons. Shankar has 45 heartbeats per minute. Manish has 70 heartbeats per minute. Raman has 50 heartbeats per minute. Shambhu has 60 heartbeats per minute. Guddu has 55 heartbeats per minute.

Read the given bar graph and answer the following : What is the average number of heartbeats per minute for the five people named on the graph.

Given graph is: A Bar Graph (also called Bar Chart) is a graphical display of data using bars of different heights. We can collect the data or information from bar graph by seeing vertical and horizontal side in heart beats (in minutes) by persons. Shankar has 45 heartbeats per minute, Manish has 70 heartbeats per minute, Raman has 50 heartbeats per minute, Shambhu has 60 heartbeats per minute and Guddu has 55 heartbeats per minute. Thus, Average number of heartbeats per minute = Sum of heartbeats number of persons = 45 + 70 + 50 + 60 + 55 5 = 280 5 = 56

Following table shows the number of trees planted after every two years in a city during the years 2005 - 2010 : Years 2005 2006 2007 2008 2009 2010 Number of trees planted 3000 2000 4000 5000 6000 3000 Express this data in the form of a bar graph, taking 1 unit length = 500 trees.

The given table is, Years 2005 2006 2007 2008 2009 2010 Number of trees planted 3000 2000 4000 5000 6000 3000 First, we draw a horizontal line and a vertical line. On the horizontal line, we will draw bars representing the number of trees planted and on the vertical line, we will write numerals representing the number of trees planted. We have to draw a bar graph to show the number of trees planted in each year. Take 1 unit length = 500 trees We get a bar graph as shown below:
