let total length of journey is x km
so,
10*x=25+(x-2)*8 (As, for first 2km 25 rupees is fixed)
then,2x=9
so,x=4.5
so option 5)4.5km is the right answer

Surit Datta   10 years AGO

First 2 Km = 25 rupees
then 8 rupees/km
so 2.5 km @ 8 rupees will be 2.5*8 rupees
which is 20 rupees
so total (2+2.5) = 4.5 km distance
and total rupees are (20+25) = 45 rupees
so the average is 10 rupees per km.
So option 5
That's it.

Rahul   10 years AGO

suppose the total distance of journey is n km
then the average rupee is given 10
so 10 = (total charge)/n
total charge = 10n
now if we subtract 25 from this total charge then the average will become 8rs per km
so,
total charge - 25/(n-2)=8
let total charge = 10n
so 10n - 25 = 8(n-2)
10n - 25 = 8n - 16
n= 4.5 km

Ans is 5) 4.5 KM
Taking option 5
First 2Km will COst = Rs 25
Then after that another 2KM will cost Rs 16
Rest remains 0.5KM so if 1KM costs Rs 8 then 0.5km will cost Rs 4
So by adding up total Cost becomes 45 (25+16+4=45).
the distance travelled is 4.5km

Let total distance travelled = x
