Question
If, on a marked price, the difference between selling
prices with a discount of 65% and with two successive discounts of 30% and 40% is ₹105, then the marked price (in ₹) is:Solution
Let the marked price be ₹x. Selling price with 65% discount = x × 0.35
Selling price with successive 30% and 40% discounts = x × 0.70 × 0.60 = x × 0.42 Difference = x × 0.42 − x × 0.35 = 105
x(0.42 − 0.35) = 105
x × 0.07 = 105
x = 105 / 0.07 = ₹1500
