Consider the following data with regard to production of cars (In lakhs):
Country A: 35 (2015), 38 (2016)
Country B: 45 (2015), 47 (2016)
Country C: 88 (2015), 93 (2016)
Country D: 75 (2015), 79 (2016)
Country E: 58 (2015), 60.9 (2016)
In which of the countries, the production of cars has increased by more than or equal to 5% in 2016 over 2015?
Elementary MathematicsPercentages
- AB and E
- BA, C and D only
- CA, C, D and E
- DA, D and E only
Explanation
Percentage growth = (2016 value − 2015 value) / 2015 value. A: 3/35 = 8.57%; B: 2/45 = 4.44%; C: 5/88 = 5.68%; D: 4/75 = 5.33%; E: 2.9/58 = 5.00% exactly, which qualifies since the bar is “more than or equal to 5%”. Only B falls short, so the qualifying countries are A, C, D and E. Hence option C.
