think it should be C. A) tells us that the article is sold for 24 Rs. so that is the selling price, which is not sufficient
B) is not sufficient by itself,but from both, the percentage lost is as much as the cost or 24/X=X/100 so we can find the cost of the article( X=cost of article)

I vote for C.

(1) It's the selling price. Don't know anything about cost. Not suff.
(2) Does say anything about what the cost and loss add up to or any fraction showing the relation.
(combined):
x = cost of article
x(x/100) = percentage loss

Selling Price = Cost - Loss
24 = x - x(x/100)
24 = x - x┬▓/100
x┬▓ - 100x + 2400 = 0

We get the value of x (cost of article) from this equation. So sufficient.
