Question
Autos in Bangalore have a fixed charge of ₹ 25 for first 2 km and variable charge of ₹ 13 per additional km. If x represents the total distance travelled, then what is the expression for the total charge?
Answer: Option B
:
B
Total distance travelled = xkm
So, the distance applicable for additional charge is(x−2)km.
∴ Total additional charge =₹13(x−2)
Total charge = Fixed charge + Additional charge
=13(x−2)+25
=13x−26+25
=₹(13x -1)
∴ Expression for total charge is ₹(13x -1).
