Question

The total capacity of a jug is 25 qt. The jug is already filled with 2/4 gal of water.
How much more water is required to fill the jug completely?

• A. 20 qt
• B. 21 qt
• C. 22 qt
• D. 23 qt

Answer 1

The correct option is D 23 qt

$\text{Capacity of the jug}$ $\text{= 25 qt}$

$\text{Water available in the tank}$ $\text{=}\frac{2}{4}\text{gal}$

$\text{Let's convert}$ $\text{gallons to quarts.}$

$\text{We know that,}$
$\text{1 gallon =}$ $\text{4 quarts}$


So,
$⟹\frac{2}{4}\text{gal =}$ $\frac{2}{4}$ $\times$ $\text{4 qt}$ $=2\text{qt}$

$\text{Hence, out of 25 qt capacity}$ $\text{of the jug, 2 qt was already filled.}$

$\text{Now we have to find the remaining}$ $\text{amount of water to be filled in}$ $\text{the jug.}$

$\text{Amount of water to be filled}$ $\text{= Total capacity - water available}$

$⟹\text{25 qt - 2 qt = 23 qt}$

$\text{Thus, 23 qt of water is required}$ $\text{to be filled in the jug.}$
