Q1.
Suppose you need to buy a book. You have ₹50 in your pocket. You visit the bookshop in your neighbourhood where the shopkeeper tells you that the book is worth ₹100. What options do you have to buy the book today?
Answer
The gap has to be closed somehow.
Price of the book = ₹100
Money in my pocket = ₹50
Shortfall = ₹100 − ₹50 = ₹50
Money in my pocket = ₹50
Shortfall = ₹100 − ₹50 = ₹50
The realistic options are:
- Pay ₹50 now and the remaining ₹50 later — if the shopkeeper agrees. This is a deferred payment.
- Borrow ₹50 from a parent, an elder sibling or a friend and pay the full amount today.
- Ask the shopkeeper to keep the book aside and come back tomorrow with the balance.
- Buy a cheaper book today that costs ₹50 or less.
- Wait and save the other ₹50 out of pocket money before buying.
- Pay digitally — if there is money in a family bank account, a UPI transfer settles the ₹100 at once.
Tip: notice that option 1 is only possible because money exists. Under barter you could not hand over “half an ox now and half an ox next month”.
