Question

The population of a place in a particular year increased by 15 % . Next year, it
decreasad by 15 %. Find the net increase or decrease percent in the initial

population.​

Answer 1

Answer:

hey mate here is your answer ,

let us assume the population to be 100

then,

15% of 100 will be 15 and increased population will be 115

now 15% decrease= 15/100×115=17.25

so, decreased population will be 115-17.25

= 97.75

so decrease percent in the initial population will be 100-97.75= 2.25

so decrease =

$\frac{2.25}{100} \times 100$

so decrease percent is 2.25%

hope it helps....... pls mark as the brainliest.

Answer 2

✰✰|| Given ||✰✰

• population increases in particular year = 15%

• population decrease next year = 15%

✰✰|| To Find ||✰✰

• net increase or decrease percent

✪|| Solution ||✪

Let, the population of place be 100

increase population = 15%/100 × 100

↬ increase population = 15

population in particular year = 100 + 15

➻ population in particular year = 115

population decrease = 15/100 × 115

➸ population decrease = 69/4

➸ population decrease = 17.25

population in next year = 115 - 17.25

⇒ population in next year = 97.25

their is decrease in next year

decrease percent = 100 - 97.25/100 × 100

↪ decrease percent = 2.25%

2.25% decrease
