Question

1. compute the compound intrest on :

Rs.1500 for 2 year at 6% per annum.​

Answer 1

Given :

Principal = Rs. 1500

Time = 2 years

Rate = 6%

To find :

Compound interest

Solution :

$\bigstar \: {\boxed{\sf{A= P\left( 1 + \frac{R}{100}\right)^{N}}}}$

$\begin{gathered}\sf{\implies} \: A= 1500\left( 1 + \dfrac{6}{100}\right)^{2} \\ \\ \sf{\implies} \: A=1500\left( \dfrac{116}{100}\right)^{2} \\ \\ \sf{\implies} \: A = 1500 \times \dfrac{116}{100} \times \dfrac{116}{100} \\ \\ \sf{\implies} \: A = 3 \times \dfrac{116}{20} \times 116 \\ \\ \sf{\implies} \: A = 3 \times \dfrac{29}{5} \times 116 \\ \\ \sf{\implies} \: A = \dfrac{10092}{5} \\ \\ \sf{\implies} \: A = 2018.4\end{gathered}$

$\bigstar \: \boxed{\sf{CI = Amount - Principal}}$★

$\begin{gathered}\sf{\implies} \: CI = 2018.4 - 1500 \\ \\\sf{\implies} \: CI = 518.4\end{gathered}$

∴ The Compound Interest is ₹ 518.4

Answer 2

Answer:

1685.40

A= Px(1+r/100)^nt

= 1500 x (1+6/100)^2

=1685.40
