Cost of $5$ kg of rice is Rs. $107.50$. What quantity of rice can be purchased in Rs. $64.5$?

Answer 1

$\therefore$ In $Rs.107.50$ quantity of rice that can be purchased = Rs. $5kg$
$\therefore$ In $Rs.1$ quantity of rice that can be purchased $=\frac{5}{107.50}kg$
$\therefore$ In $Rs.64.5$ quantity of rice that can be purchased $=\frac{5}{107.50}\times 64.5$
$=\frac{5}{10750}\times 100\times \frac{645}{10}=3kg$
