      A invested Rs X in a scheme. After 6 months, B

      joined with Rs 15000 more than that of A. After an year, ratio of profit of B to the total profit was 3: 7. Find the value of X.
      A Rs. 35000 Correct Answer Incorrect Answer
      B Rs. 30000 Correct Answer Incorrect Answer
      C Rs. 32000 Correct Answer Incorrect Answer
      D Rs. 33000 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Profit of B/Total Profit = 3/7 = ((X + 15000 )×6)/(X × 12 + (X + 15000 ) × 6)
      9X + 45000 = 7X + 105000
      2X = 60000
      X = 30000
