Question

Cost of $4$ dozen bananas is $Rs.180$. How many bananas can be purchased for $Rs.37.50$?

Answer 1

$1$ dozen contains $=12$ items
$\therefore$ $4$ dozen contains $=12\times item=48$ items
Cost of $4$ dozen bananas $=Rs.180$
$\therefore$ Number of bananas that can be purchased for $Rs.1=\frac{48}{180}$
$\therefore$ Number of bananas that can be purchased for $Rs.37.50$
$=\frac{48}{180}\times 37.50=\frac{48}{180}\times \frac{3750}{100}=10$
