Question

$70$ patients in a hospital consume $1350$ liters of milk in $30$ days. At the same rate, how many patients will consume $1710$ liters of milk in $20$ days.

Answer 1

Given, $70$ patients consume $1350$ lt of milk in $30$ days and say $x$ patients consume $1710$ lt of milk in $20$ days.

In that case,

$\frac{70\times 30}{1350}=\frac{x\times 20}{1710}$

$\Rightarrow x=\frac{70\times 30\times 171}{1350\times 2}=133$
