      A 20,000 Correct Answer Incorrect Answer
      B 60,000 Correct Answer Incorrect Answer
      C 30,000 Correct Answer Incorrect Answer
      D 25,000 Correct Answer Incorrect Answer

      Solution

      ATQ,

      Let, the present population be ‘x’.

      ATQ,

      Future population = 1.18 × 1.18 × x = 41472

      Or, x = 41472 × (1/1.18) × (1/1.18)

      So, x = 30,000

      Therefore, present population = x = 30,000
