Question
A man sold an article after
giving two successive discounts of 10% and 'd'%. If his profit from the transaction is ₹42.6, find the value of 'd' given that the marked price of the article is ₹840 and the cost price is ₹600.Solution
ATQ, Selling price of the article = Rs. 642.6 Overall discount % = {(840 – 642.6)/840} × 100 = 23.5% So, 10 + d – 10d/100 = 23.5 10 + d – 0.1d = 23.5 0.9d = 13.5 d = 15 So, the value of ‘d’ = 15%
