Data represented by double bar graph is as follows:
(i) Jammu has the largest difference in temperature i.e., Maximum temperature = 41oC and Minimum temperature = 26oC.
Therefore, Difference = 41oC – 26oC = 15oC
(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 - 28oC
Minimum temperature of two cities whose minimum temperature is higher than the maximum temperature of Bangalore are Ahemedabad and Jaipur = 29oC
(iv) Mumbai has the least difference in temperature i.e., Maximum temperature = 32oC and Minimum temperature = 27oC
Therefore Difference = 32oC – 27oC = 5oC
