Answer 1

Answer: Rs 22781.25

Step-by-step explanation:

R = 12.5 % 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(1+\frac{R}{100})^{n}

A = 16000(1+\frac{12.5}{100})^{3}

A = 16000(1.125)^{3}

A = 22781.25

Thus, the required amount is Rs 22781.25
