7. The railway distances of four cities from New Delhi (in km) are given below. City Bhubaneswar Kolkata Guwahati Patna 1650 HANDLING Distance from New Delhi (in km) 1430 1820 Draw a bar graph to represent the above data and answer the following questions. 1. Which city out of the given four cities is closest to New Delhi? il. How much farther is Guwahati from New Delhi than Bhubaneswar from New Delhi? 980
Answers
We can draw the bar graph by following these steps:
Step 1. On a graph paper, draw a horizontal line OX and a vertical line OY. These two lines represents the x-axis and the y-axis respectively.
Step 2. Along OX, write the name of the cities at points taken at uniform gaps.
Step 3. Choose the scale: 1 small division = 10km
1 big division = 100km
Step 4. Then, the heights of the various bars are:
Kolkata = 13 big divisions and then 4 small divisions = 134 small divisions
Mumbai = 11 big divisions = 110 small divisions
Chennai = 17 big divisions = 170 small divisions
Hyderabad = 12 big divisions and then 2 small divisions = 122 small divisions
Step 5. On the x-axis, draw bars of equal width and heights obtained in step 4 at the points marked in Step 2.
The completed bar graph is shown below
