Ram sold 2 items A and B at the same price. Profit on one and incurring loss on the other. Ratio between the total S.P. of both items together and total cost price of both items together is 30 : 37. If he earns 25% profit on selling A, what was the loss incurred in selling of B in Rs. 600?

Explanation

Ram sold both the items at same selling price. Selling price of item B = Rs. 600 ⇒ Selling price of item A = Rs. 600. He earns 25% profit on selling item A ⇒ Cost price of item A = 600 × 100/125 = Rs. 480. Let the cost price of item B be Rs. x. The ratio of selling price of both the items and the cost price of both the items is 30 : 37 ⇒ 1200/(480 + x) = 30/37 ⇒ x = 1000. ∴ Loss incurred on selling item B = 1000 – 600 = Rs. 400.
