Gary bought 5 cars with an investment of Rs.500000 and started renting them. Fuel charges are Rs.50/km

and he pays Rs.5000 as the salary to each driver of the car. If the average run of each car in a month is

200km, how much should be charged per km to get his investment in 15 years?

• it should be charged Rs 77.7 per km in 15 years.
  sol:
  5 cars investment -500000 ,1 cars investment-100000
  average run of 5 cars =200*5=1000 fuel charges =50*1000
  driver salary=25000 ( for 5 cars)
  total spending(inluding fuel's charges)=25000+50000=75000
  15 years=180 months
  so,180*(x*1000)-180*(75000)=500000
  x=77.7 / km

• total spending on one car in one month is.......
  driver charge=5000 and fuel=50*200=10000
  now total spend on car i.e driver n fuel=15000/per month
  now extra cost is required get car price
  and price of one car is ..........100000
  hence in 15 yr ........................100000/(15*12)=5000/9 per month
  hence total require amount in one month is 5000+10000+5000/9...........for 200 km
  so.......for 1 km.................5000+10000+5000/9
  ------------------------------- =77.7
  200
