      Question

      The contributions made by A and B are in the ratio of

      2:5. If 10% of total profit is donated and A gets 8100 as his share of profit, what is the total profit?
      A Rs. 30000.25 Correct Answer Incorrect Answer
      B Rs. 30000 Correct Answer Incorrect Answer
      C Rs. 38406.25 Correct Answer Incorrect Answer
      D Rs. 31500 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Let the total profit = x
      The ratio of contribution by A and B = 2:5
      Share of A = (2/7) × x = 8100
      x= (8100 × 7)/2
      Total profit: x = 28350
      A gets 8100 after 10% donated
      Now, 90% = 28350
      1% = 28350/ 90
      And, 100% = (28350/90) × 100 = 31500
