    • Question

      Three series I, II and III, are given below, which

      contain a missing term 'P', 'Q' and 'R' respectively. Series I: 12, 13, 17, 44, P, 3425 Series II: 12.8, 32, 80, 200, 500, Q Series III: 15, 40, R, 170, 291, 460 Which of the following statement(s) is/are true? I. 'R' is completely divisible by 3 II. (P + 2Q) > 452 III. Product of each digit of 'P' is 126
      A Both I and II Correct Answer Incorrect Answer
      B Only II Correct Answer Incorrect Answer
      C Both II and III Correct Answer Incorrect Answer
      D Both I and III Correct Answer Incorrect Answer
      E All I, II and III Correct Answer Incorrect Answer

      Solution

      Series I: 12 + 1¹ = 13 13 + 2² = 17 17 + 3³ = 44 44 + 4⁴ = 300 300 + 5⁵ = 3425 'P' = 300 Series II: 12.8 × 2.5 = 32 32 × 2.5 = 80 80 × 2.5 = 200 200 × 2.5 = 500 500 × 2.5 = 1250 'Q' = 1250 Series III: 15 + 5² = 40 40 + 7² = 89 89 + 9² = 170 170 + 11² = 291 291 + 13² = 460 'R' = 89 Statement I: 'R' = 89 89 is not completely divisible by 3. So, Statement I is false. Statement II: P + 2Q = 300 + 2 × 1250 = 300 + 2500 = 2800 2800 > 45² So, Statement II is true. Statement III: Product of each digit of 'P' = 3 × 0 × 0 = 0 So, Statement III is false. Therefore, Only II is true.
