Question

A district consists of a urban area and a rural area. The temperature of the respective areas are recorded at different time of the day and tabulated as follows: Temperature ${(}^{o}C)$ Time Urban Area Rural Area 1730 1830 1930 2030 2130 2230 2330

26	25
25	24
24	23
23	22
23	22
22	21
21	21

Plot a double line graph and choose the same from the given options.

• A.
• B.
• C.

Answer 1

The correct option is C

According to the tabulated data at 1730, urban area has a temperature of ${26}^{o}C$, while rural area has a temperature of ${25}^{o}C,$ and so on.

We plot line graphs of the temperatures corresponding to each type of areas and merge them to obtain a double line graph.

Here, each data set is indicated with different color and/format.

It is evident from the given data that the temperature of the urban area is overall more than the rural area.

$\therefore$ The upper line graph indicates the data for the urban area.
This is depicted by option (c) with a proper marking of the plot.
