Effective discount = 20 + 15 - (20×15)/100 = 35 - 3 = 32%
If SP = ₹450 and discount = 10%, then MP × 0.9 = 450. MP = 450/0.9 = ₹500
SP = 2000 × 1.15 = 2300.
Increase = 6000. Percentage = (6000/30000) × 100 = 20%.
40% of MP = 480. MP = 480/0.4 = 1200.
Let C = 100. B = 110. A = 1.2 × 110 = 132. A is 32% more than C.
Item 1: SP = 900 at 25% profit, CP₁ = 900/1.25 = 720. Item 2: SP = 900 at 25% loss, CP₂ = 900/0.75 = 1200. Total CP = 1920, Total SP = 1800. Loss = 120.
Initial price × 1.16 = 465. Initial price = 465/1.16 = 400.
Let C = 100. B = 80. A = 100. Wait: B = 80, A = 1.25 × 80 = 100. So A = C. Hmm, let me recalculate: If B is 20% less than C, B = 0.8C. A is 25% more than B, so A = 1.25B = 1.25 × 0.8C = C. So A = C. But answer says B is correct. Let me verify: A = 1.25B, B = 0.8C. A = 1.25 × 0.8C = C. A/C = 1. So A is 0% more. This doesn't match. The answer should be C.
CP = 100, MP = 180, SP = 144 (for 44% profit). Discount = 180 - 144 = 36. Discount% = (36/180) × 100 = 20%.
