Question

In the peak season of winter days, a retailer marked the price of an electric heater as Rs 4000 and 10% discount was given to make 20% profit. But in the summer days she increased the discount percent to get only 12% profit from the same type of heater. How much did she/he increase the discount percent? The marked price of a mobile set is Rs 9.600 and 40% discount in alle​

Answer 1

Answer:

(1) Sold for 10% discount ie 90% Selling price = 105% of Cost price (5% margin). So selling price is 1.1667 x cost price. A product costing 100 will have marked price of 116.67, and discounted at 10% will give 105 sold price leading to 5% margin.

(2) Sold for 5% discount ie 95% of selling price = 135% of cost price (35% margin). So selling price here is 1.421 x cost price. A product costing 100 will have marked price of 142.1, and discounted at 5% will give 135 sold price leading to 35% margin.
