 Hi and welcome to the session. I am Deepika here. Let's discuss the question. Take the data giving the minimum and maximum temperature of various cities given in the beginning of this chapter. Plot a double bar graph using the data and answer the following. Part 1, which city has the largest difference in the minimum and maximum temperature on the given date. Part 2, which is a hotter city and which is a colder city. Part 3, name two cities where maximum temperature of one was less than the minimum temperature of the other. Part 4, name the city which has the least difference between its minimum and the maximum temperature. Now, this is suitable giving the minimum and maximum temperature of various cities given in the beginning of this chapter. And the part, maximum temperature as on 2006 was 38 degree centigrade and minimum 29 degree centigrade. Maximum 37 degree centigrade and minimum 26 degree centigrade. Bangalore 28 degree centigrade, 21 degree centigrade, Chennai 36 degree centigrade and 27 degree centigrade, Delhi 38 degree centigrade and 28 degree centigrade, Japan 39 degree centigrade and 29 degree centigrade, Jammu 41 degree centigrade and 26 degree centigrade, Mumbai 32 degree centigrade and 27 degree centigrade. Now, this is a bar graph using the data. The vertical line shows the temperature of cities and the horizontal line represents the various cities. Scale is 1 unit is equal to 10 degree centigrade. First bar represents the maximum temperature and the second bar represents the minimum temperature. So, let's start the solution part 1. Now, see the bars representing the maximum temperature and the minimum temperature. We see the largest difference is seen between the bar representing the maximum temperature and minimum temperature for the city Jammu. Hence, the answer for part 1 is Jammu. That is, the Jammu has the largest difference in minimum and maximum temperature on the given date. See the bar graph carefully. Now, see the bar representing the maximum temperature. Now, we observe that the bar representing the maximum temperature of the city Jammu is tallest. Hence, Jammu is the hottest city and the bar representing the minimum temperature of Bangalore is smallest. Hence, Bangalore is the coldest city. The answer for the above question is Jammu is the hottest city. Bangalore is the coldest city. This is the answer for part 2. Part 3, see the bars representing the maximum temperature and compare it with the bars with the minimum temperatures of the other cities. We see that the bar representing the maximum temperature of Bangalore is smaller in length to the bar representing the minimum temperature of Jaipur. Similarly, the bar representing the maximum temperature of Bangalore is smaller in length to the bar representing the minimum temperature of Antapar. Hence, the answer for this part is Bangalore and Jaipur. Bangalore, answer for part 3, representing the maximum and minimum temperature of different cities. We see for the city Mumbai, there is a least difference between the bar representing the maximum temperature and minimum temperature. Hence, the answer for part 4 is Mumbai. The question is clear to you. Why I take care?
