Question

The graph of Tiger Population from Years $(2015-2020)$ is

And Rhino Population from Years $(2015-2020)$ is

Answer the following questions.
$\left(1\right)$ Has the Rhino population increased, and if so, by how much?
$\left(2\right)$ Whose population is greater in $2018$, and by how much?

• A. $\left(1\right)16$
  $\left(2\right)8$
• B. $\left(1\right)8$
  $\left(2\right)16$
• C. $\left(1\right)20$
  $\left(2\right)10$
• D. None of the above

Answer 1

The correct option is A $\left(1\right)16$

$\left(2\right)8$

$\left(1\right)$ We see the Rhino population's graph that the population has increased from $2015-2020$.

Population in $2015=16$

Population in $2020=32$

Rhino's increased population
$=32-16$
$=16$

So, Rhino's population has increased by $16.$


$\left(2\right)$ Rhino's population in $2018=28$

Tiger's population in $2018=20$

Hence, Rhino's population is greater than Tiger's population in $2018$.

And Rhino's population is greater by $28-20=8$
