Question

If the cost of $3\frac{2}{3}$ litres of juice is ₹$104\frac{1}{2}$, find the cost per litre.

Answer 1

We will first convert mixed fraction into improper fraction.

$\text{Cost of 3}\frac{2}{3}\text{litres of milk = ₹104}\frac{1}{2}$

$\Rightarrow \text{Cost of}\frac{11}{3}\text{litres of milk = ₹}\frac{209}{2}$

$\Rightarrow \text{Cost of 1 litre of milk =}\frac{209}{2}÷\frac{11}{3}$

$\Rightarrow \text{Cost of 1 litre of milk =}\frac{209}{2}\times \frac{3}{11}$

$=₹\frac{209\times 3}{2\times 11}$

$=₹\frac{57}{2}$

$=₹28\frac{1}{2}$
