There is mistake in your question .
 it should be x litres of fuel per kilometer
and then x+5 litres of fuel per kilometer.
solution:
           Distance traveled before servicing the car =  400 km
           fuel consumed per kilometer (in litres)= x
   therefore total fuel consumed before servicing of car = 400*x

  Distance traveled after servicing the car =  400 km
fuel consumed per kilometer (in litres)= x +5
  therefore total fuel consumed after servicing of car = 400*(x+5)
                                                                           =400x +2000

hence total fuel consumed = 400x + 400x +2000
                                       = 800x +2000
         Since the data provided by the question is not sufficient to evaluate the value of x . Hence we get the answer in terms of x.

Hope This helps you!!
