Answer» SOLUTION:CASE ILet initial cost price be x Rs.Profit = 20/100 * x = x/5So selling price = x + x/5 = 6x/5 CASE IICost price = x + 50Selling Price = 6x/5 + 30Profit = (6x/5 + 30) - (x + 50) = x/5 -20Profit Percentage = (x/5 - 20) / (x + 50) * 100But in according to the question profit percentage = 20 - 10/3 = 50/3 %So (x/5 - 20) / (x + 50) * 100 = 50/3∴ (x/5 - 20) / (x + 50) = 1/6∴ 6x/5 - 120 = x + 50∴ x/5 = 170∴ x = 850So original cost price = Rs 850 |
