Question 5 (c)
Following is the list of temperatures of five places in India, on a particular day of the year
Place Temperature
Siachin 10∘C below 0∘C ___
Shimla 2∘C below 0∘ ___
Ahmedabad 30∘C above 0∘ ___
Delhi 20∘C above 0∘ ___
Srinagar 5∘C below 0∘ ___
Which is the coolest place?
In the question above we are given a list of cities and their temperature on a particular day.
First, we will convert the temperatures into integers. We will take 0∘ as the reference, any temperature above that will be positive and any temperature below that will be negative.
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
As we know the higher the numerical value of a negative integer, lower will be its value.
Among −10∘C, −2∘C and −5∘C, −10∘C is the lowest temperature.
Siachin with −10∘C is the coolest place.
