Question

Harry is eight times as heavy as a stone. A stone is $25$ pounds in weight. Calculate Harry's weight in ounces and tonnes.

• A. 3200 ounces
• B. 3201 ounces
• C. 0.1 ton
• D. 0.2 ton

Answer 1

Answer: (A), (C)

0.1 ton

Weight of stone $=25$ pounds
Weight of Harry = 8 x Weight of each stone
$=8\times 25$
$=200$ pounds

As we know,
1 pound = 16 ounces
$\therefore$ 200 pounds $=200\times 16$
200 pounds $=3200$ ounces

Also,
$1\text{ton}=2000\text{pound}$
$1\text{pound}=\frac{1}{2000}\text{ton}$
$200\text{pound}=\frac{200}{2000}=0.1\text{ton}$
Hence, weight of Harry is 3200 ounces or 0.1 ton.
