Step-by-step explanation:

since rate of increasing population is 10%.

so the population of town 1 year ago was = 90% of 22000

                                                                    = 90/100 x 22000

                                                                    = 9/10 x 22000

                                                                      =   9 x 2200

                                                                        = 19800
