x =135000/40

x = 3375

Explanation: Population in a small town last year = 50000

Population in a small town after one year = 63750

Increase in population = 63750 - 50000 = 13750

Therefore,

percentage increase in population = Increase in population/Last year population × 100 %

= 1375000/50000

= 27.5%

Thus, the increase in population is 27.5%
