The bar graph given below shows the production of
television and refrigerator in a factory for given years. Which of the following statement(s) is/are correct? I. Production of refrigerator in 1993 is 11.11 percent more than the production of television in 1991. II. Average production of television during 1990-1994 is 5000.Solution
From Statement I: Required % = (5000 – 4500)/4500 × 100 = 11.11% Statement I is true From Statement II: Required average = (5500 + 4500 + 6500 + 7000 + 6500)/5 = 6000 Statement II is false. Hence, only statement I is true.
