Profit, Loss and Discount

Let MP be 100. After 35% discount, SP = 65. Loss is 7.14% (1/14), so CP = SP / (1 - 1/14) = 65 / (13/14) = 70. If 20% discount is given, SP = 80. Profit = 80 - 70 = 10. Profit % = (10/70) * 100 = 14.28%.

Marked price = 700. Discount 20% means selling price = 700 * 0.8 = 560. Profit 40% means cost price * 1.4 = 560. Cost price = 560 / 1.4 = 400.

Let CP = x. Gain percent = x. Selling Price = CP + (Gain percent/100) * CP = x + (x/100) * x = 144. x^2 + 100x - 14400 = 0. Factoring gives (x + 180)(x - 80) = 0. Since CP must be positive, x = 80.

Selling price = 5500 * (1 + 0.0909) = 5500 * 1.0909 = 6000. If 6000 is the price after a 20% discount, then 0.8 * Marked Price = 6000. Marked Price = 6000 / 0.8 = 7500.

SP = 5400, Discount = 10%. Marked Price (MP) = 5400 / 0.9 = 6000. Cost Price (CP) = 5200. Markup = (6000 - 5200) / 5200 = 800 / 5200 = 8/52 = 2/13 approx 15.38%.

Profit = 9375 - 7500 = 1875. Profit percentage = (1875 / 7500) * 100 = 25%.

Profit = Selling Price - Cost Price = 1500 - 1200 = 300. Profit percentage = (Profit / Cost Price) * 100 = (300 / 1200) * 100 = 25%.

Selling Price = Cost Price * (1 - loss percentage). 8400 = CP * 0.75. CP = 8400 / 0.75 = 11200.

Selling price is 3960 after a 12% discount on marked price (MP). So, 0.88 * MP = 3960, which means MP = 4500. The markup is the difference between MP and cost price (3600), which is 900. Markup percentage = (900 / 3600) * 100 = 25%.

Let MP be the marked price. 25% of MP - 20% of MP = 500, so 5% of MP = 500. MP = 10000. Rahim bought it at 20% discount, so he paid 80% of 10000 = 8000.

Cost price of 1 orange = 1/10 = 0.10. Selling price of 1 orange = 1/8 = 0.125. Profit = 0.125 - 0.10 = 0.025. Profit percentage = (0.025 / 0.10) * 100 = 25%.

Selling price = 3600 * 1.15 = 4140. If this is after an 8% discount on marked price (MP), then 0.92 * MP = 4140. MP = 4140 / 0.92 = 4500.

Let CP = x. Marked Price = 2760. Discount = 15%, so SP = 0.85 * 2760 = 2346. Profit = 20%, so SP = 1.2 * CP. 1.2 * CP = 2346, so CP = 2346 / 1.2 = 1955.
