Price of old scooter       = 4700/-
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.)

cost price of the scooter = Rs. 4700
money spent on its repairs = Rs. 800
therefore , total cost price = Rs. 5500
selling price of the scooter = Rs. 5800
profit made = selling price - cost price
= Rs. (5800 - 5500)
= Rs. 300
therefore , profit percent = (profit  /  cost price ) * 100
= (300 / 5500)*100
= 5.45 %

There is nothing wrong in my answer. If you round of 4, it becomes 5. thats all.
