Answer 1

Weight of each bag = 38 kg and 400 g

Let's convert the weight into a single unit.

We know, 1,000 g = 1 kg
$\Rightarrow$ 1 g = $\frac{1}{1000}$ kg
$\Rightarrow$ 400 g = $\frac{400}{1000}$ kg = 0.4 kg

$\therefore$ Weight of each bag
= 38 kg + 0.4 kg
= 38.4 kg

Weight of 50 bags
= $50\times 38.4$ kg
= $5\times 10\times \frac{384}{10}$ kg
= $5\times 384$ kg
​​​​​= $1,920$ kg

Weight of the spaceship = 1,480 kg

Total weight of 50 bags and spaceship
$=\text{Weight of 50 bags}+\text{Weight of the spaceship}$
$=1,920\text{kg}+1,480\text{kg}$


$\therefore$ Combined weight is 3,400 kg.
