Question

$8$ parcels weigh $12\mathrm{kg}$. How many parcels will weigh $60\mathrm{kg}$?

Answer 1

Given:
The weight of $8$ parcels = $12\mathrm{kg}$
$\therefore$ Weight of $1$ parcel = $\frac{12\mathrm{kg}}{8}=\frac{3}{2}\mathrm{kg}$
Number of parcels that contains 60 kg weigh = $\frac{60kg}{{\displaystyle \frac{3}{2}}kg}$$=\frac{60\times 2}{3}=40$
So, $40$ parcels contain the weight $60\mathrm{kg}$.
