#### Question 1:

This bar graph shows the maximum temperatures in degrees Celsius in different cities on a certain day in February. Observe the graph and answer the questions.
(1) What data is shown on the vertical and the horizontal lines?
(2) Which city had the highest temperature?
(3) Which cities had equal maximum temperatures?
(4) Which cities had a maximum temperature of 30°C?
(5) What is the difference between the maximum temperatures of Panchgani and Chandrapur?

(1) Temperature is shown on the vertical line (Y-axis) and different cities are shown on the horizontal line (X-axis).

(2) Chandrapur had the highest temperature (35°C) as the height of the bar corresponding to city Chandrapur is maximum.

(3) Panchgani and Matheran had equal maximum temperature of 25°C. Also, Pune and Nasik had equal maximum temperature of 30°C. Thus, the cities Panchgani and Matheran; Pune and Nasik had equal maximum temperatures.

(4) Pune and Nasik had a maximum temperature of 30°C.

(5) Maximum temperature of Panchgani = 25°C

Maximum temperature of Chandrapur = 35°C

∴ Difference between the maximum temperatures of Panchgani and Chandrapur = 35°C − 25°C = 10°C

#### Question 6:

Yashwant gives different amounts of time as shown below, to different exercises he does during the week. Draw a bar graph to show the details of his schedule using an appropriate scale.
 Type of exercise Running Yogasanas Cycling Mountaineering Badminton Time 35 Minutes 50 minutes 1 hr 10 min 112$1\frac{1}{2}$ hours 45 minutes

Steps to draw the bar graph:
