Question

10 pounds of cargo needs to be loaded on a truck. The truck has a capacity of 100 ounces.
How much cargo will remain unloaded?

• A. 30 oz
• B. 40 oz
• C. 50 oz
• D. 60 oz

Answer 1

The correct option is D 60 oz

$\text{Cargo to be loaded on a truck = 10 lb}$

$\text{Capacity of the truck = 100 oz}$

$\text{Let's convert pounds to ounces.}$

$\text{We know that,}$
$\text{1 pound =}$ $\text{16 ounces}$


$\text{Hence, we will multiply 10 with 16.}$

$\text{So, 10 lbs}=10\times 1\text{lb}$
$=10\times 16\text{oz}$
$=160\text{oz}$
To calculate the amount of cargo left unloaded, we have to subtract the amount of cargo to be loaded from the total capacity of the truck.

$⟹$ $\text{Total amount of cargo}$ $\text{- Capacity of the truck}$

$⟹$ $\text{160 oz - 100 oz = 60 oz}$

$\text{Hence, 60 oz of cargo is left unloaded.}$
