Ramesh bought a calculator with 20% discount on the tag price. He obtained 10% profit by selling it for Rs.440. What was the tag price ?

Explanation

Let tag price = Rs. 100x Discount % = 20% 20 => Calculator's selling price = Cost price for Ramesh = 100x − ( 100 × 100x) = 100x − 20x = Rs. 80x 10 Profit = 100 × 80x = Rs. 8x (5) Also, selling price = (80x + 8x) = 440 440 => x = 88 = 5 ∴ Tag price = 100 × 5 = Rs. 500 => Ans - (A)
