Hint: First, we will use the concepts of the number line. On a number line, which is on the left are smaller than the number which is present on the right-hand side.

Complete step-by-step answer:
We are given that there are five different cities on the number line Kasauli, Manali, Nainital, Ooty and Bangalore.

If we see the number line, there are numbers on the left and right of zero, which is supposed to be at the center.
We know that the numbers on the left of the zero on the number line are negative, whereas numbers on the right of the zero on the number line are positive.
Now in this figure, there are three cities on the left side and two on the right side.
So when the temperature is measured, we know that the number of the most left of the number line, that is, most negative or minimum temperature is the coldest place and the most right of the number line, that is, most positive or maximum temperature is the hottest place.
Now finding the temperatures of the Kasauli from the above number line, we get
\[ \Rightarrow {\text{Kasauli}} = - 9^\circ \]
Now we will be finding the temperatures of the Manali from the above number line, we get
\[ \Rightarrow {\text{Manali}} = - 7^\circ \]
Now finding the temperatures of the Nainital from the above number line, we get
\[ \Rightarrow {\text{Nainital}} = - 3^\circ \]
Now we will be finding the temperatures of the Ooty from the above number line, we get
\[ \Rightarrow {\text{Ooty}} = 15^\circ \]
Now we will be finding the temperatures of the Bangalore from the above number line, we get
\[ \Rightarrow {\text{Bangalore}} = 20^\circ \]
So, we have seen the city with the highest temperature in Bangalore.

Note: A pictorial representation of numbers evenly marked on a straight line is a number line. We need to make sure the points on a line are equal distance towards the right side of the number 0 and the left hand side of the number 0 in the number line. Do not get confused that the negative numbers always come on the left hand side of the number line. When we go on the left of the number line, the numbers start getting smaller. Mark the numbers really carefully on the number line.
