100/108 = Rs. 2500New SELLING price = Rs. 3000∴ profit PERCENTAGE = (3000 - 2500)/2500 × 100% = 20%Detailed Solution:Let, cost price = 100xProfit = 8%∴ Selling price = 100x + 8x = 108xAccording to the question,⇒ 108x = 2700⇒ x = 25∴ Cost price = 100x = 100 × 25 = 2500New selling price = Rs 3000∴ Profit percentage = (3000 - 2500)/2500 × 100% = 500/2500 × 100% = 20%
