Explanation : Given, Ravi purchase two articles for ₹1500 each. Total CP = ₹3000. Ravi gets 6% profit on first article, then SP of 1st article = 1500 + 1500 x 6/100. = ₹1590. After selling 2nd article, he loses 4%. Then, SP of 2nd article = 1500 - 1500 x 4/100. = ₹1440. ∴ Total amount after selling of both article = 1590 + 1440 = ₹3030. ∴ profit % = 30/3000 x 100% = =1 %.
