Question

Autos in Bangalore have a fixed charge of Rs. 25 for the first 2 km and then an additional charge of Rs.13 per each additional km. If $x$ represents the distance travelled, find an expression for the total charge.

• A. 13$x$ + 1
• B. 13$x$ - 1
• C. 25 + 13$x$
• D. None of these

Answer 1

The correct option is B 13$x$ - 1

$x$ represents the distance travelled. So, the distance applicable for additional charge is $x$-2.
$\therefore$ Total additional charge = 13($x$ - 2)
Therefore, total charge = Additional chrage + Fixed charge
= 13($x$-2) + 25
= 13$x$ - 1
