The given table shows marks obtained by Riya and Siya in their semester examination. Represent the given data on a double bar graph and answer these questions: English Hindi Mathematics Science Social science Riya 80 85 85 90 75 Siya 75 75 85 80 85 In which subjects was Riya better than Siya?

Given table: English Hindi Mathematics Science Social science Riya 80 85 85 90 75 Siya 75 75 85 80 85 As we know that, A double bar graph is used to compare two types (sets) of data simultaneously. It helps us to present more than one kind of information at the same time. Let us draw a double bar graph for the data given. We select a scale of 1 unit = 10 marks . Hence, from the above double bar graph, Clearly, In English, Hindi and Science subjects Riya scored more marks than Siya ∴ Riya scored better than Siya in English, Hindi and Science subjects
