After knowing that what does a bar graph represent we read the scale so that we can know the precise values in the given data.<br>After reading a bar graph one must be able to draw certain conclusions from it. Drawing some conclusions from a given bar graph means interpretation of the bar graph.<\/p>\n<p>Question 2.<br>Read the following bar graph and answer the following questions:<br>(i) What information is given by the bar graph?<br>(ii) In which year the export is minimum?<br>(iii) In which year the import is maximum?<br>(iv) In which year the difference of the values of export and import is maximum?<br><img src=\"https:\/\/farm2.staticflickr.com\/1948\/30707327907_88f6f653fd_o.png\" alt=\"Class 9 Maths Chapter 23 Graphical Representation of Statistical Data RD Sharma Solutions\" width=\"520\" height=\"416\"><br>Solution:<br>After reading the bar graph.
