Comparison of two activities (walking and cycling) is to be represented, therefore double bar graph is drawn by taking the school along x - axis and number of children along y - axis , using scale of 1 cm = 5 children. Therefore, the required graph is,

Draw an appropriate graph to represent given information. Teams From Champions Trophy to World cup- 06 Last 10 ODI in 07 South Africa 75 % 78 % Australia 61 % 40 % Sri Lanka 54 % 38 % New Zealand 47 % 50 % England 46 % 50 % Pakistan 45 % 44 % West Indies 44 % 30 % India 43 % 56 %

To compare the percentage win in ODI achieved by various teams, we represent the data by a double-bar graph. We represent the teams along the x-axis and their 'percentage win' along y-axis, using the scale 1 cm = 5 %
