Question

The population of the town increased from 175000 to 262500 in a decade. What is the average percent increase of population per year?

Answer 1

5%

Explanation:

As given,

The population of the town increased from 175000 to 262500 in a decade.

⇒ In 10 years , population increased from 175000 to 262500

⇒% increase =
`(262500 - 175000)/(175000)`× 100% =
`(87500)/(175000)`×100% = 0.5×100% = 50%

Now,

Average % increase =
`(percent increase)/(Total years)` =
`(50)/(10)`% = 5%

∴ we get

Average percent increase of population per year = 5%
