Question

The taxi charges in a city comprises of a fixed charge together with the charge for the

distance covered. For a journey of 6 km, the charge paid is `58, while for a journey of 10

km, the charge paid is `90. Find the charge per km and the fixed charge.?

Answer 1

let fixed charge be=X
let charge for distance covered be=y
at first,
X+6y=58
in second situation,w
X+10y=90
subtracting both equations

we get y=8
then putting the value of y in one of the equations we get
X =10
