Question

$4$ packets of rice weigh $18\mathrm{kg}$. How many packets will weigh $27\mathrm{kg}$ of rice?

Answer 1

Given: $18\mathrm{kg}$ of rice packed in $4$ packets
By unitary method
$1\mathrm{kg}$ of rice packed in $\frac{4}{18}$packets
Packets require for $27\mathrm{kg}$ = $27\times \frac{4}{18}=6$
So, $6$ packets will weigh $27\mathrm{kg}$ rice.
