Correct option is D
• Cost price of oven (CP) = Rs. 25,000
• Selling price of oven (SP) = Rs. 29,500
• Overheads = Rs. 1,500
Total Cost Price = CP + Overheads
Total Cost Price = 25,000 + 1,500 = 26,500
Gain = SP - CP
Gain = 29,500 - 26,500 = 3,000
Gain percentage = × 100
Gain percentage = × 100 = 11.32% ≈ 11%
