Solution:

Let population of town initially = 100x
Population after 44% increase in 1st year =

100x + 44 /100 × 100x = 144x

Population after 75% increase in 2nd year =

144x +75 / 100 × 144x = 252x

Thus, rate of increase in population =

(252x−100x)/{100x} × 100 = 152%

⇒ Average rate of increase in the population in 2 years =

152/2=76%
