The table shows information about the population of a city.

Population in 2001 Population in 2011
420 000 480 000

Liam claims,

   “From 2011 to 2021 the population of the city will increase by
   the same percentage as from 2001 to 2011”

He works out,

   population increase from 2001 to 2011 = 480 000 – 420 000

                                                                        = 60 000

                                         population in 2021 = 480 000 + 60 000

                                                                        = 540 000
