The bar graph given below shows the data on the production of milk products (in thousand tonnes) by three branches, X, Y, and Z, of a dairy product company over the years. Study the graph and answer the question. For which branch(es) of the dairy product company was the average production for the given 4 years the minimum?

Explanation

Solution The question requires us to find the branch with the minimum average production of milk products (in thousand tonnes) over four years (2018 to 2021). Data Analysis: From the bar graph, we note the production data for each branch: Branch X: 50 (2018), 45 (2019), 45 (2020), 55 (2021) Branch Y: 35 (2018), 45 (2019), 40 (2020), 45 (2021) Branch Z: 45 (2018), 50 (2019), 50 (2020), 60 (2021) Calculate the Average Production for Each Branch: Branch X: (50 + 45 + 45 + 55) / 4 = 195 / 4 = 48.75 Branch Y: (35 + 45 + 40 + 45) / 4 = 165 / 4 = 41.25 Branch Z: (45 + 50 + 50 + 60) / 4 = 205 / 4 = 51.25 Conclusion: The minimum average production over the four years is for Branch Y, with an average of 41.25 thousand tonnes.
