Answer:
32 percent
Explanation:
Assume the town's population in 1989 is 100. In 1995 it will be 120. There's a 10% increase (12) from 1995 to 2003 so the population in 2003 is 132. The percentage increase from 1989 (100) to 2003 (132) is (132-100) / 100 = .32 or 32 percent.
The percentage increase in the population between 1989 and 2003 will be 32%.
What is the percentage?
The quantity of anything is stated as though it were a fraction of a hundred.
The population of a town increased by 20% between 1989 and 1995. If the population increased again by 10% from 1995 till 2003.
Then the percentage increase in the population between 1989 and 2003 will be
Let x be the population in 1989.
Then the population in 1995 will be
⇒ 1.2 x
Then the population in 2003 will be
⇒ 1.2 × 1.1 × x
⇒ 1.32x
Then the percentage will be
P = (1.32x - x) / x × 100
P = 0.32 × 100
P = 32%
