Question

Noah lost $1,500$ g of weight. Earlier, he used to weigh $66.5$ kg. How much does Noah now weigh in pounds?

• A. $150$
• B. $142$
• C. $140$
• D. $143$

Answer 1

The correct option is D $143$

Earlier weight $=66.5\text{kg}$
Weight lost $=1,500\text{g}$

$\because 1\text{g}=\frac{1}{1,000}\text{Kg}\Rightarrow 1,500\text{g}=\frac{1,500}{1,000}\text{Kg}=1.5\text{kg}$

So, the weight of Noah
$=66.5-1.5$ kg
$=65$ kg

Now, $\because 1\text{kg}=2.2\text{lbs}$
$\Rightarrow 65\text{kg}=65\times 2.2\text{lbs}=143\text{lbs}$

So, the weight of Noah $=65\text{Kg}=143\text{lbs}$
