Compound Interest

Question:

What sum will amount to ₹24494.40 in 2 years at 8 % per annum, if compound interest is compounded annually?

Options:

₹21200

₹22400

₹21000

₹22000

Correct Answer:

₹21000

Explanation:

The Formula that we used here is -

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

24494.40 = P [ 1 + \(\frac{8}{100}\)]²

24494.40 = P [  \(\frac{27}{25}\)]²

24494.40 = P × \(\frac{27}{25}\)  × \(\frac{27}{25}\)

P = 21000
