Equivalent discount = 20 + 5 − 20 × 5 % = 24% 100 ∴ CP of article = ₹ 25000 × 76 = ₹ 19000 100
Repairs cost = ₹ 1000
∴ Actual CP = 19000 +1000 = ₹ 20000
SP = ₹ 25000
Profit = 25000 –20000 = ₹ 5000∴ Gain% = 5000 × 100 = 25% 20000 Correct Option: B

∴ Loss = ₹ (25 – 24) = ₹ 1S.P. of remaining 1 stock 4 = (60% of 120) × 1 = ₹ 18 4
∴ Loss = ₹ (25 – 18) = ₹ 7
