Question

An elephant, on average, drinks 200 L of water in a day. If a glass holds approximately 25 cL of water, calculate the number of glasses of water consumed by the elephant in a day.

• A. 800 glasses of water.
• B. 400 glasses of water.
• C. 8 glasses of water.

Answer 1

The correct option is A 800 glasses of water.

In a day, the quantity of water drank by an elephant $=200\text{L}$

We know,
$1\text{L}=100\text{cL}$
$\Rightarrow 200\text{L}=200\times 100\text{cL}$

Capacity of a glass $=25\text{cL}$

$\therefore$ Number of glasses of water drank by the elephant
$=\frac{\text{Total amount of water drank in a day}}{\text{Capacity of a glass}}$

$=\frac{200\times 100\text{cL}}{25\text{cL}}$

$=\frac{25\times 8\times 100\text{cL}}{25\text{cL}}$
(cancelling $25$ from numbertor and denominator)

$=800$

$\therefore$ The elephant drinks 800 number of glasses of water each day.
