Compound Interest

Question:

A sum of ₹900 is invested at compound interest (compounded annually) for 2 years. If the rate of interest is 10% per annum, then what will be the amount?

Options:

₹1071

₹1089

₹1289

₹1121

Correct Answer:

₹1089

Explanation:

The Formula that we used here is -

Amount = P$(1 \;+\; \frac{R}{100})^t$

 = 900 [ 1 + \(\frac{10}{100}\)]²

 = 900 [  \(\frac{11}{10}\)]²

= Rs. 1089
