Answer 1

Answer:

Principal=3000 ₹ is correct answer

Step-by-step explanation:

Amount=4177.20 ₹

Rate=18% compounded annually

Time= 2 years

Principal=?

$amount = p(1 + \frac{r}{100}) {}^{n}$

$4177.20 = p(1 + \frac{18}{100}) {}^{2}$

$4177.20 = p(1 + \frac{9}{50}) {}^{2}$

$4177.20 = p( \frac{50 + 9}{50}) {}^{2}$
