A taxi charges a fare of Rs 2550 for a journey of 150 km. How much would it charge for a journey of 124 km?

Let the charge for a journey of 124 km be ₹x.

Price(in ₹)	2550	x
Distance(in km)	150	124

More is the distance travelled, more will be the price.
So, it is a case of direct proportion.
$$\begin{gathered} \therefore \frac{2550}{150}=\frac{x}{124} \\ \Rightarrow x=\frac{2550\times 124}{150}=2108 \end{gathered}$$
Thus, the taxi charges ₹2,108 for the distance of 124 km.
