      If u : v = 6 : 11, determine the ratio (u + 2v) : (2u +

      v)
      A 28:23 Correct Answer Incorrect Answer
      B 24:25 Correct Answer Incorrect Answer
      C 18:23 Correct Answer Incorrect Answer
      D 17:20 Correct Answer Incorrect Answer

      Solution

      ATQ,

      Let the values of ‘u’ and ‘v’ be ‘6k’ and ‘11k’ respectively.

      So, required ratio = {6k + (2 × 11k)} : {(2 × 6k) + 11k}

      = {6k + 22k} : {12k + 11k}

      = 28k : 23k

      = 28 : 23
