      Question

      Which of the following is true about the relation

      between the wrong numbers in the following series? I: 10, 18, 29, 40, 54, 70 II: 15, 24, 34, 48, 63, 80 a. The difference between the wrong term of I and II when divided by 5 leaves the remainder 0. b. 2/3 of the sum of the wrong numbers is divisible by 3. c. 21 is added to the wrong number in I, then divided by 2, so the difference between the number obtained and wrong number of II is an odd number.
      A Only I Correct Answer Incorrect Answer
      B Only I & II Correct Answer Incorrect Answer
      C Only II & III Correct Answer Incorrect Answer
      D All I, II & III Correct Answer Incorrect Answer
      E None of I, II & III Correct Answer Incorrect Answer

      Solution

      ATQ, The wrong numbers are: Series I wrong term = 29 Series II wrong term = 34 Now check the statements: Statement I Difference between wrong terms = 34 - 29 = 5 5 Γ· 5 gives remainder 0 So, Statement I is true Statement II Sum of wrong numbers = 29 + 34 = 63 2/3 of 63 = 42 42 is divisible by 3 So, Statement II is true Statement III 21 is added to wrong number in I: 29 + 21 = 50 50 Γ· 2 = 25 Difference between 25 and wrong number of II = 34 - 25 = 9 9 is an odd number So, Statement III is true Hence, all I, II and III are correct.
