80*7=560/-
60*5=300/-
now for a 300 km journey 300-(80+60)=160 km left.
(160/5)*11=352/-[As every 5 km costs Rs. 11/-]
So total cost=560+300+352=1212/-

Charges of a car for first 80km= 80*7= 560
Charges of car for next 60km= 60*5= 300

Hence the charges for 140km= 560+300= 860.

Now the remaining journey is= 300-140= 160km
Price for every 5km= 11rs

So the price for remaining 160km journey= (160/5)*11= 352rs

Hence total charges= 352+860= rs 1212
