The names of the heads of some families in a village and the quantity of drinking water their family consumes in one day are given below. Draw a bar graph for this data.

(Scale: On Y-axis, 1cm = 10 litres of water)

Name |
Ramesh |
Shobha |
Ayub |
Julie |
Rahul |

Litres of water used | 30 litres | 60 litres | 40 litres | 50 litres | 55 litres |

#### Solution

**Steps to draw the bar graph:**

(1) In the centre of the graph paper, write the title "Heads and quantity of drinking water consumed".

(2) Draw the X-axis and Y-axis, and mark O, their point of intersection.

(3) Write the names of the head of the families on the X-axis at equal distances.

(4) The quantity of the drinking water consumed is taken on the Y-axis.

(5) Write the scale in the top right-hand corner i.e. 1 cm = 10 litres of water on the Y-axis.

(6) Draw a bar of the appropriate height above the name of each head of the family on the X-axis.
