a shopkeeper has goods of worth Rs. 6000. He sold half of the goods at a gain of 12%. At what profit percent should he sell the remaining half of the stock so that he gets 18% profit on the whole

24?

assume he brought it for 100 each i.e a total of 200 and he gets a profit of 18% on whole i.e. 236.Now,he sells 100 of it at 12% profit i.e. 112.So,total we need 236 i.e 236-112=124 so,the answer will be 24%
