Answer 2

➤ Given :-

Original population :- 20000

Population after change :- 1600

➤ To Find :-

Percentage of decreased population.............

➤ Formula required :-

${\large \tt \dashrightarrow \orange{\boxed{ \tt \gray{\dfrac{Decreased \: Value}{Original \: Value} \times 100}}}}$

➤ Solution :-

First, we should find the decreased value of the population by subtracting the original population change and population after change............

${\tt \longrightarrow 20000 - 1600}$

$\tt \longrightarrow 18400$

Now,

Percentage of decreased population :-

${\tt \longrightarrow \dfrac{18400}{20000} \times 100}$

${\tt \longrightarrow \dfrac{18400 \times 100}{20000} = \dfrac{1840000}{20000}}$

${\tt \longrightarrow \cancel \dfrac{1840000}{20000} = \boxed{ \tt 92 \bf\%}}$

$\Huge\therefore$The percentage of decreased population is 92 $\bf\%$.
