Question

The taxi charges in city comprises of fixed charges together with the charge for the distance
covered. For a journey of 13km, the charge paid is Rs.129 and for a journey of 22km, the charge
paid is Rs.210. What will a person have to pay for travelling a distance of 32km?

Answer 1

Answer:

Let the fixed charge be Rs x and

The charges for per km be Rs y

Therefore

x + 12 y = 89 ......... eqn 1

And

x + 20 y = 145 ........eqn 2

1 - 2

x + 12 y - x - 20 y = 89 - 145

8 y = 56

y = 7

Therefore x + 20 (7) = 145

x + 140 = 145

x = 5

Now , for 30 km

x + 30 y = 5 + 30 * 7

= 5 + 210

= 215
