Question

Take the data giving the minimum and the maximum temperature of various cities given in the beginning of this Chapter. Plot a double bat graph using the data and answer the following:

Temperature of Cities as on 20.6.2006

City	Ahmedabad	Amritsar	Bangalore	Chennai
Max.  Min.	38oC 29oC	37oC 26oC	28oC 21oC	36oC 27oC
City	Delhi	Jaipur	Jammu	Mumbai
Max. Min.	38oC 28oC	39oC 29oC	41oC 26oC	32oC 27oC

(i) Which city has the largest difference in the minimum and maximum temperature on the given data?

 (ii) Which is the hottest city and which is the coldest city?

(iii) Name two cities where maximum temperature of one was less than the minimum temperature of the order.

(iv) Name the city which has the least difference between its minimum and the maximum temperature.

Answer 1

Data represented by double bar graph is as follows:

(i) Jammu has the largest difference in temperature i.e., Maximum temperature = 41^oC and Minimum temperature = 26^oC.

Therefore, Difference = 41^oC – 26^oC = 15^oC

(ii) Jammu is the hottest city due to maximum temperature is high and Bangalore is the coldest city due to maximum temperature is low.

(iii) Maximum temperature of Bangalore - 28^oC

Minimum temperature of two cities whose minimum temperature is higher than the maximum temperature of Bangalore are Ahemedabad and Jaipur = 29^oC

(iv) Mumbai has the least difference in temperature i.e., Maximum temperature = 32^oC and Minimum temperature = 27^oC

Therefore Difference = 32^oC – 27^oC = 5^oC
