Answer» Given that the PRESENT population of the town is 22000 The population of the town increased by 10% We have to find the population of the town a year ago So let the population of town a year ago be 'A' We will find 110% of x because in order to find percentage INCREASE (100+x)/100 where x is the percentage increase in population. A × (100×10)/100 =22000 A × 110/100 = 22000 A= (22000× 100) /110 A= 20000 HENCE the population of the town a year ago was 20000. Thanks |
