C Correct answer
Explanation

The question asks for the cost of an article sold at 50% discount. (i) Selling at Rs 500 less gives no profit/loss, meaning SP - 500 = CP. (ii) MP = 3 * CP. (iii) SP = 1.5 * CP. Since SP = 0.5 * MP, (ii) implies SP = 0.5 * 3 * CP = 1.5 * CP. Thus, (ii) and (iii) are identical statements. Either one is redundant.

AI explanation

The question provides the discount as 50%, meaning the selling price is half of the marked price. Statement (ii) gives the marked price as 3 times the cost, which means selling at a 50% discount yields a selling price of 1.5 times the cost, immediately allowing us to find the base cost. Statement (iii) independently states the selling price is 1.5 times the cost, providing the exact same proportional information as statement (ii) and making both independently sufficient alongside the given discount. Therefore, either statement (ii) or statement (iii) can be dispensed with.
