Question

If the cost of $10kg$ of wheat is $Rs170.50$, then :

_____ $kg$ of wheat can be purchased for $Rs102.30$

Answer 1

Given that,

cost of $10kg$ of wheat $=$ $Rs170.50$

Assume, $x$ $kg$ of wheat can be purchased for $Rs102.30$

In proportion , it can be written as

$10kg:x::Rs170.50:Rs102.30$

Therefore,

$$\begin{gathered} \frac{10kg}{x}=\frac{107.50}{102.30} \\ x=\frac{102.30\times 10}{107.50}kg \\ x=9.5kg \end{gathered}$$

Hence, $9.5kg$ of wheat can be purchased for $Rs102.30$
