Question

The mass of a Tyrannosaurus is $14,500$ kg and the average mass of an adult human is $80$ kg $400$ g. Will the mass of $150$ people equal to that of the Tyrannosaurus?

• A. Yes
• B. No
• C. Cannot say

Answer 1

The correct option is B No

Mass of the Tyrannosaurus
$=14,000\text{kg}$

Average mass of an adult human
$=80\text{kg}400\text{g}$

Let's calculate the total mass of $150$ people.

So, the total mass of $150$ people
$=80\text{kg}400\text{g}\times 150$


$\Rightarrow 80\text{kg}400\text{g}\times 150=12,000\text{kg}60,000\text{g}$

Note:
$1\text{Kg}=1000\text{g}1\text{g}=\frac{1}{1000}\text{kg}$

$\Rightarrow 60,000\text{g}=\frac{60,000}{1000}\text{kg}=60\text{kg}$

$\Rightarrow$ Weight of the $150$ people
$=12,000\text{Kg}+60\text{kg}$
$=12,060$ kg
Answer:

Weight of the $150$ is not equal to the weight of the Tyrannosaurus.
