According to the table shown above,
We are given the temperature of five places in India on a particular day.
Now, consider 0∘ as the reference temperature value. Any temperature above that will be considered positive and any temperature below that will be considered negative.
The table given below shows the temperature of different places in the form of integers according to the convention.
Place Temperature
Siachin 10∘C below 0∘C = −10∘C
Shimla 2∘C below 0∘ = −2∘C
Ahmedabad 30∘C above 0∘ = +30∘C
Delhi 20∘C above 0∘ = +20∘C
Srinagar 5∘C below 0∘ = −5∘C
Thus, The number line representing the temperature in degrees Celsius of the cities is shown below:
