उत्तर

Given: 
P = Rs 2, 400
R = 20 % p . a . 
n = 3 years
We know that amount A at the end of n years at the rate R % per annum when the interest is 
compounded annually is given by A = P\[ \left( 1 + \frac{R}{100} \right)^n . \]
\[ \therefore A = 2, 400 \left( 1 + \frac{20}{100} \right)^3 \]
\[ = 2, 400 \left( 1 . 2 \right)^3 \]
\[ = 4, 147 . 20\]
Thus, the required amount is Rs 4, 147 . 20 .
