      Question

      The population of a town is 24000. In the first year, it

      increases by 25%. In the second year, it decreases by 10%. After that, 3000 people migrate to the town. What is the final population?
      A 45000 Correct Answer Incorrect Answer
      B 30000 Correct Answer Incorrect Answer
      C 66500 Correct Answer Incorrect Answer
      D 27500 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Initial population = 24000 After 25% increase: = 24000 + 25% of 24000 = 24000 + 6000 = 30000 After 10% decrease: = 30000 - 10% of 30000 = 30000 - 3000 = 27000 After migration of 3000 people: = 27000 + 3000 = 30000 Hence, the correct answer is 30,000.
