      35% of β€˜u’ added to 65% of β€˜v’ results in 130.

      A 10 Correct Answer Incorrect Answer
      B 35 Correct Answer Incorrect Answer
      C 50 Correct Answer Incorrect Answer
      D 32 Correct Answer Incorrect Answer

      Solution

      According to the question, 0.35u + 0.65v = 130…….. (1) And, v – u = 70……. (2) On solving equation (1) and (2), we get u = 80 and v = 150 Therefore, (2u – v) = 160 – 150 = 10
