Mr. Kapoor compares the prices (in ₹) of different items at two different shops A and B. Examine the following table carefully and represent the data by a double bar graph.

Items	Price (in ₹) at shop A	Price (in ₹) at shop B
Tea-set	900	950
Mixer	700	800
Coffee-maker	600	700
Dinner set	600	500

Steps:

1. On a graph paper, draw two mutually perpendicular lines OX and OY which intersect each other at point O.

   The line OX is taken horizontal and is called the x-axis, whereas the line OY is taken vertical and is called the y-axis.

2. On the x-axis, starting from O, mark points at equal distances. At these points write the names of the different items given. In this question, the names are Tea-set, Mixer, Coffee-maker and Dinner set.

3. Along y-axis, mark the heights of the bars (rectangles) in proportion to the given data (Prices at Shop A and B).

4. Remember:

   (i) The heights of different bars (rectangles) are parallel to y-axis and the mid-points of their bases are on the points marked on the x-axis (step 2).

   (ii) The bars may be taken of any suitable width, but widths of all the bars must be the same.

   (iii) The space (distance) between consecutive bars may be of any suitable value, but the spaces between all the consecutive bars must be the same.

The required double bar graph is as given below:
