SP = 2,000 × 0.8 × 0.9 × 0.95 = 2,000 × 0.684 = ₹1,368.
SP = ₹5 at 10% loss. CP = 5/0.9 = ₹5.556. For 15% gain: SP = 5.556 × 1.15 = ₹6.39 ≈ ₹6.38.
MP = 10,000 × 1.5 = ₹15,000. SP = 15,000 × 0.9 = ₹13,500. Net amount received = 13,500 - 500 = ₹13,000. Profit = 3,000. Wait, recalculating: Profit = 13,000 - 10,000 = ₹3,000. But with gift valued, profit = ₹2,500.
Let CP of 1 item = x. Then 12x = 10 × SP. SP = 1.2x. Profit = 20%.
CP of 200 eggs = (200/12) × 12 = ₹200. SP = (120 × 1.5) + (80 × 1) = 180 + 80 = ₹260. Profit = 60/200 × 100 = 25%.
SP = MP × 0.8 × 0.85 = MP × 0.68 = 1,292. MP = 1,292/0.68 = ₹1,900.
CP per book = 400/5 = ₹80. SP per book = 400/4 = ₹100. Profit = 20/80 × 100 = 25%.
Article 1: CP₁ = 1200/1.2 = ₹1,000. Article 2: CP₂ = 1200/0.8 = ₹1,500. Total CP = ₹2,500, Total SP = ₹2,400. Loss = 4%.
