Explanation:
• Since, my friend has won the lottery and assuming she has won the big amount, I advice her to decide based on the "interest rate".
• We can receive payments in lump sum but once again we have to analyze where we are going to invest the amount and what kind of returns it will give.
• Once again in payments over time, we have to check about the returns.
• These two can be checked based on the interest. So returns are calculated based on yearly / monthly interest.
So, we have to take decision based on the interest rate only
