Answer

Cost of 124 km journey = ₹ 1395.

Cost of 1 km journey = ₹ (1395124)[Less distance, Less cost]\Big(\dfrac{1395}{124}\Big) \quad \text{[Less distance, Less cost]}

Cost of 240 km journey = ₹ (1395124×240)[More distance, More cost]\Big(\dfrac{1395}{124} \times 240\Big) \quad \text{[More distance, More cost]}

= ₹ 11.25 x 240 \quad (Dividing 1395 and 124 by 124)

= ₹ 2700

Hence, a journey of 240 km will cost ₹ 2700.
