Answer 2

Given -

• Amount = Rs. 2360
• Time = 3 years
• Rate = 12%

To find -

• Principal.

Solution -

Amount = $\sf{P \bigg[1 + \dfrac{r}{100} \bigg]^n}$

where,

• P = Principal
• R = Rate
• n = time

Substitute the given values.

$\sf{2360 = P \bigg[1 + \dfrac{12}{100} \bigg]^3}$

$: \implies\sf{2360 = P \bigg[1 + \dfrac{6}{50} \bigg]^3}$

$: \implies\sf{2360 = P \bigg[1 + \dfrac{3}{25} \bigg]^3}$

$: \implies\sf{2360 = P \bigg[ \dfrac{25 + 3}{25} \bigg]^3}$

$: \implies\sf{2360 = P \bigg[ \dfrac{28}{25} \bigg]^3}$

$: \implies\sf{P = 2360 \times \dfrac{25}{28} \times \dfrac{25}{28} \times \dfrac{25}{28}}$

$: \implies\sf{P = \: Rs. \: 1,679.80}$
