Question

An auto rickshaw charges Rs 10 for the first kilometre then Rs 8 for each such subsequent kilometre. The total charge (in Rs) for d kilometres is ______.

Answer 1

An auto rickshaw charges Rs 10 for the first kilometre then Rs 8 for each such subsequent kilometre. The total charge (in Rs) for d kilometres is 2 + 8d.

Explanation:

For the first kilometre, rickshaw charges = Rs. 10.

And the charges for subsequent kilometre = Rs. 8.

∴ The charges for d kilometres

= 10 + (d – 1)8

= 10 + 8d – 8

= 2 + 8d
