How taxi driver made money?

One of myfriend send me a good story.......
.....................I was in a cab on my way to work. Only, my cab was stuck in a traffic jam with Himmesh Reshamiya's latest song blaring into my ears. In an attempt to kill the radio, I started talking to my cab driver.

In the course of my chat, he told me the taxi he was driving was his own. Not only that he also owned six other fiat taxis, one Toyota Qualis, which he hired out. Now, he's debating buying a truck or a bus.

Wow! Really? I asked him where he got the money from... slightly, nervous that I was riding with a possible hit man for Dawood. And his answer was even more surprising.

He said "Madam, whenever you need to go some place you take a cab and go. While, I park my taxi some place and hop into a bus."
I listened as he crunched some numbers for me.

He asked: "How much does it cost to travel from your home to your office?"

"Rs 100", I said.

"Well, Rs 200 for a round trip?", he continued, "Let's say, you travel through the month by taxi. How much would that cost you?"

Rs 6,000!, I said.

"The bus ticket costs you Rs 10 and say another Rs 20 to get from your home to the bus stop. That’s Rs 60 per day for a round trip. You are saving Rs 140 everyday. That's Rs 4,200 a month, nearly Rs 50,000 a year. If you invested that in something, you'd be able to buy your own car!”

What could I say? I, now, travel by bus. And, am doing a Systematic Investment Plan in a mutual fund and paying a monthly premium in a Unit linked insurance plan.

What I could not do in 18 months, a taxi driver had done in 18 minutes.
