................................................
Let the population of the town a year ago be x.
According to question,
x + 18% of x = 934560
=> x + 18/100 × x = 934560
=> x + 9x/50 = 934560
=> 50x + 9x/50 = 934560
=> 59x = 934560 × 50
=> x = 934560 × 50/59
=> x = 15840 × 50
=> x = 792000
Hence the population of the town a year ago is 792000.
