Directions: Study the given information and answer the following question.
A car servicing company has ten LED boards which are fitted on a wall. Each of them displays the digits from 0-9. They are programmed in such a way that when any car enters the workshop for service, the registration number on the car's number plate will appear on the wall as the digits on the wall-mounted LED boards shall glow to show a 4-digit number. On Monday, 4 cars of different colours, i.e. red, white, black and grey, entered the workshop. Due to faulty software, the only thing that got noted down was the number of times each LED board glowed in total after the 4 cars entered. Hence, the following data was collected.

Further, software provided the following data:
(1) The registration number of each car has a factor 5.
(2) Except the white car, all the other cars have at least three different digits.
(3) The registration number of black car has the highest value numerically.
(4) The registration number of red car has four different digits, three of which are not present in the registration numbers of any of the other 3 cars.
(5) The difference between the registration numbers of red car and grey car has a maximum value of 600 and a minimum value of 500.
(6) The registration number of white car is exactly a factor of the registration number of black car.
(7) The sum of the digits of registration number of white car is 8.
