Q:

In the question given below, three paragraphs are given, which are jumbled. Find the correct sequence of these paragraphs so that they form a meaningful passage.
A. The power of compounding works the way it does because you are reinvesting the interest that you earn back into the instrument, besides giving it time to grow. Let’s simplify it further. Say in the first year you invest ₹100 and you get 10% annual return of ₹10. Next year, along with ₹110 (the first year principal amount and the interest amount), you will put another ₹100. The ₹10 you earned as interest gets reinvested, helping you grow your money faster.

B. To get a perspective, let’s turn to some numbers. Say you started investing ₹3,000 a month when you were 25, and go on till you are 60. At an average annual rate of 7% returns, your corpus will grow to ₹53.24 lakh. If you decide to start investing at the age of 35 years, even if you put aside double the amount— ₹6,000 per month — till the age of 60, the value of your corpus will be only ₹48.72 lakh. The example shows that you would need half the amount to get more in returns if you start investing early.
C. Adulting can’t wait when it comes to savings and investing. Why you may ask? If you delay your investments, how will you see the magic of compounding? When it comes to investing, you need to start early. In fact, you should start saving and investing as soon as you start earning. Compounding allows you to build a bigger corpus with a smaller amount.

A) BAC B) CAB
