Form the pair of linear equations for the problems and find their solution by substitution method:
The taxi charges in a city consist of a fixed charge together with the charge for the distance covered. For a distance of 10 km, the charge paid is Rs. 105 and for a journey of 15 km, the charge pair is Rs. 155. What are the fixed charges and the charge per km? How much does a person have to pay for travelling a distance of 25 km?

Text Solution

Verified by Experts

The correct Answer is:
fixed charge is =Rs. 5, distance covered = Rs. 10 per km. Total charge = Rs. 255
