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

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

(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 other.

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

Here,

The bar graph of the given data can be created as follows:

(i) Here,

According to the question,

We have to find the city with the largest difference in its maximum and minimum temperature.

Therefore,

We can observe that,

From the graph,

The largest difference between the maximum and minimum bars is of Jammu.

Hence,

It can be concluded that,

Jammu is city with the largest difference in its maximum temperature and minimum temperatures on 20.06.2006

(ii) Here,

According to the question,

We have to find the hottest and coolest city from the given cities while looking into the graph.

And,

We know that,

Hottest city would have the maximum temperature

And,

Coolest city would have the least temperature.

Therefore,

We can observe that,

From the graph,

The highest bar of maximum temperature is of Jammu.

Hence,

Jammu is the hottest city.

And,

The lowest bar of minimum temperature is of Bangalore,

Hence,

Bangalore is the coolest city among the given cities.

(iii) Here,

According to the question,

We have to find the two cities where maximum temperature of one was less than the minimum temperature of the other.

Therefore,

We can observe that,

From the graph,

Bangalore has its maximum temperature as 28°C

Whereas,

The minimum temperature of the following two cities is 29°C

Jaipur

And,

Ahmedabad

Hence,

It can be concluded that the required pair of two cities are,

Bangalore and Jaipur

And,

Bangalore and Ahmedabad

(iv) Here,

According to the question,

We have to find the city with the least difference in its maximum and minimum temperature.

Therefore,

We can observe that,

From the graph,

The least difference between the maximum and minimum bars is of Mumbai.

Hence,

It can be concluded that,

Mumbai is city with the least difference in its maximum temperature and minimum temperatures on 20.06.2006
