      Question

      S1 is a series of 5 consecutive multiples of 3 and S2 is

      a series of 4 consecutive multiples of 8. If the ratio of 3rd to 2nd terms in S1 is 6:5 and in S2 is 5:4, what is the sum of the first digits of S1 and S2?
      A 28 Correct Answer Incorrect Answer
      B 24 Correct Answer Incorrect Answer
      C 30 Correct Answer Incorrect Answer
      D 36 Correct Answer Incorrect Answer

      Solution

      Let S1 be x, (x + 3), (x + 6), (x + 9) and (x + 12)
      Let S2 be y, (y + 8), (y + 16) and (y + 24)
      So, (x + 6)/(x + 3) = 6/5
      x = 12
      Also, (y + 16)/(y + 8) = 5/4
      y = 24
      So, required sum = 12 + 24 = 36
