Question

The cost of 10 kg weight is Rs 225, the cost of 8 kg of wheat is?

Answer 1

`\begin{equation*} Rs180 \end{equation*}`

Step-by-step explanation

To find the cost of 8kg of wheat, we have to apply proportions.

Let the cost of 8 kg of wheat be x.

We can write that:

`\begin{gathered} 10kg=Rs225 \\ 8kg=x \end{gathered}`

To solve for x, cross-multiply:

`\begin{gathered} x*10=8*225 \\ x=(8*225)/(10) \\ x=Rs180 \end{gathered}`

That is the cost of 8 kg of wheat.
