      Question

      A total of Rs. ‘K’ was to be distributed among L, M,

      and N in ratio of 2:5:3 respectively but due to some reason the money was falsely distributed in ratio of 3:5:2 respectively such that N received Rs. 3600 less. Find the value of 2K.
      A ₹72000 Correct Answer Incorrect Answer
      B ₹68400 Correct Answer Incorrect Answer
      C ₹75600 Correct Answer Incorrect Answer
      D ₹69000 Correct Answer Incorrect Answer
      E ₹70200 Correct Answer Incorrect Answer

      Solution

      Let the total amount [K] be Rs. 10x
      So, amount which N was supposed to receive = 10x × (3/10) = Rs. 3x
      Amount which was actually received by N = 10x × (2/10) = Rs. 2x
      ATQ,
      3x - 2x = 3600
      ⇒ x = 3600
      Also,
      K = 10x = 10 × 3600 = Rs. 36000
      Therefore, required value,
      2K = 2 × 36000 = ₹72000
