IB exams John buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, what is his gain percent?

Answer»

f old SCOOTER       = 4700/-Additional money spent = 800/-So, total price                 = 4700 + 800                                       = 5500/-Selling price                    = 5800/-Gain                                = 5800 - 5500                                        = 300/-Gain %                            = (Gain/ Total price) × 100                                        = (300/5500) × 100                                        = 5.45% = 5.5%(After the decimal, If a number 5 or greater than 5 comes, You can round off the previous number by adding 1 to it. It is OPTIONAL.)
