AI explanation

Let the marked price be M and the cost price be C, where the selling price is 0.85M. From statement I, 0.15M is Rs. 4,000, so M is 4000 divided by 0.15, equaling Rs. 26,666.67. From statement II, 0.85M equals C minus 2000, so C is 0.85M plus 2000. If we dispense with statement III and use I and II, we can find the profit percentage by calculating (0.85M minus C) divided by C. This proves that any one of the three statements can be dispensed with while still solving the problem.
