A dialogue between a house wife and a hawker
    House-wife: Excuse me.
    Hawker: Yes, please. Can I help you?
    W: I'd like to buy vegetables. Do you have onions?
    H: Here they are. How much?
    W: How much per kg?
    H: They are Rs. 20/kg?
    W: Gosh. Very expensive. Yesterday I bought them Rs.16/kg.
    H: You are right. I also sold them at the same rate yesterday. But today, the rate is very high at the market.
    W: What about cabbage? How much is it?
    H: It is Rs. 10/kg. It is quite fresh.
    W: Everything is very expensive.
    H: What is cheaper now-a-days?
    W: It is very hard for a poor-man to survive.
    H: All the day we move in street and in the evening hardly we make Rs. 100 or 150.
    W: Okay please give me 1kg onion and 1/2 kg cabbage. Coriander leave for one rupee.
    H: Here you are.
    W: How much?
    H: It's Rs. 20.
    W: Here's the money.
    H: Thank you.
