Question

The gross weight of a package and its contents is 11 pounds 5 ounces. If the packaging weighs 1 pound 15 ounces, what's the net weight of the contents? A. 12 lb. 20 oz. B. 10 lb. 5 oz. C. 10 lb. 6 oz. D. 9 lb. 6 oz.

Answer 1

Answer: Option 'D' is correct.

Explanation:

Since we have given that

$\text{gross weight of a package }\\\\= 11\text{ pounds }5\text{ ounces}\\\\=11\times 16+5\text{ ounces}\\\\=176+5\text{ ounces}\\\\=181\text{ ounces}$

If the weight of the packaging is given by

$1\text{ pounds }15\text{ ounces}\\\\=1\times 16+15\text{ ounces}\\\\=31\text{ ounces}$

So, our net weight will be

$181\text{ ounces}-31\text{ounces}\\\\=150\text{ ounces}$

Now we'll change it into pounds

$\frac{150}{16}=9\text{ pounds }6\text{ ounces}$

Hence, Option 'D' is correct.
