Question

The following data gives the minimum and maximum temperature (in $^\circ {\text{C}}$) of the cities on a particular day. Plot a double bar graph from this data and answer the question.

City	Delhi	Bangalore	Srinagar	Mumbai	Chennai
Maximum Temperature (in $^\circ {\text{C}}$)	23	20	10	30	32
Minimum Temperature (in $^\circ {\text{C}}$)	20	19	4	28	27

(a) Which city has the maximum difference in day’s temperature?
(b) Which city has the minimum difference in day’s temperature?
(c) Which are the hottest and coldest cities?

Answer 1

take the names of the cities on horizontal X axis and maximum and minimum temperatures of the cities on vertical Y axis. Plot a double bar graph of this data and answer the questions given using the information from the graph.

Complete Step by step answer: The following data given gives the information about the maximum and minimum temperatures of different cities.

City	Delhi	Bangalore	Srinagar	Mumbai	Chennai
Maximum Temperature (in $^\circ {\text{C}}$)	23	20	10	30	32
Minimum Temperature (in $^\circ {\text{C}}$)	20	19	4	28	27

Plot a double bar graph of this data by taking the names of the cities on the horizontal X axis and maximum and minimum temperatures of the cities on the vertical Y axis.

(a)
The maximum temperature of the Srinagar city is $10^\circ {\text{C}}$ and the minimum temperature is $4^\circ {\text{C}}$.
Hence, the temperature difference of the Bangalore city is $6^\circ {\text{C}}$ which is greater than the temperature difference of any other cities.
Hence, Srinagar city has the maximum difference in day’s temperature.

(b)
The maximum temperature of the Bangalore city is $20^\circ {\text{C}}$ and the minimum temperature is $19^\circ {\text{C}}$.
Hence, the temperature difference of the Bangalore city is $1^\circ {\text{C}}$ which is lesser than the temperature difference of any other cities.
Hence, Bangalore city has the minimum difference in day’s temperature.

(c)
Among the maximum temperatures of all the cities, the city Chennai has the maximum temperature as $32^\circ {\text{C}}$ which is more than the maximum temperature of any other cities.
Therefore, the city Chennai has the hottest temperature.
Among the minimum temperatures of all the cities, the city Srinagar has the minimum temperature as $4^\circ {\text{C}}$ which is more than the minimum temperature of any other cities.
Therefore, the city Srinagar has the coldest temperature.

Note: The students should keep in mind that minimum and maximum temperatures of a city should be plotted adjacent to each other. The students may plot the minimum and maximum temperature of a city at different positions. Also the students should keep in mind that the temperature differences asked in first and second parts should be the temperature difference for the same city.
