# Profit and Loss- Aptitude Questions and Answers

 A man bought a horse and a cart. If he sold the horse at 10 % loss and the cart at 20 % gain, he would not lose anything; but if he sold the horse at 5% loss and the cart at 5% gain, he would lose Rs. 10 in the bargain. The amount paid by him was Rs._______ for the horse and Rs.________ for the cart? A) 400,200 B) 200,400 C) 500,300 D) 300,500 Correct Answer : 400,200 Explanation :Let x be the cost price of the horse and y be the cost price of the cart. In the first sale there is no loss or profit. (i.e.) The loss obtained is equal to the gain. Therefore (10/100) * x = (20/100) * y x = 2 * y -----------------(1) In the second sale, he lost Rs. 10. (i.e.) The loss is greater than the profit by Rs. 10.Therefore (5 / 100) * x = (5 / 100) * y + 10 -------(2) Substituting (1) in (2) we get (10 / 100) * y = (5 / 100) * y + 10 (5 / 100) * y = 10 y =cost price of the cart = 200 From (1) x= 2 * 200 =cost price of the horse = 400 Post/View Answer Post comment Cancel Thanks for your comment.!
