Answer» Correct Answer - Option 3 : \({\left( {\frac{b}{{10}}} \right)^2}\) Given: The selling price of each article = Rs. a Gain on one article = b% Loss on another article = b% Concept used: Where there is a profit of x% and loss of y% in a transaction then the resultant profit or loss per cent is given by [x - y - xy/100] Calculations: Here x = y = b (b - b - b × b/100) = -b2/100 ⇒ -(b/10)2 -ve sign means loss occurred ∴ The loss is (b/10)2 |
