Question

principal =5000,rate =8%,time =2year find CI​

Answer 1

Answer:

A = P × ( 1 + R/100)^ N

A = 5000 × (1 + 8/100)²

A = 5000 × ( 1 + 2/25)²

A = 5000 × (27/25)²

A = 5000 × 27/25 × 27/25

A = 8 ×27 × 27 ( dividing 5000 by 25 two times)

A = 5832

CI = Amount - Principal

CI = 5832 - 5000

CI = 832

Compound Interest = 832

Answer 2

Answer:

The Compound Interest is Rs. 832.

Step-by-step explanation:

Given :

Principal = Rs. 5000

Rate = 8%

Time = 2 years

To find :

The compound interest

Solution :

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

$\tt{\implies} \: A = 5000 \times \left( \dfrac{8}{100} + 100\right)^{2} \\ \\ \tt{\implies} \: A = 5000 \times \left (\dfrac{108}{100} \right)^{2} \\ \\ \tt{\implies} \: A = 5000 \times \left (\dfrac{27}{25} \right)^{2} \\ \\ \tt{\implies} \: A = 5000 \times \dfrac{27}{25} \times \dfrac{27}{25} \\ \\ \tt{\implies} \: A = 200 \times 27 \times \dfrac{27}{25} \\ \\ \tt{\implies} \: A = 8 \times 27 \times 27 \\ \\ \tt{\implies} \: A = 5832$

Amount = Rs. 5832

$\rule{300}{1.5}$

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

$\tt{\implies} \:CI = 5832 - 5000 \\ \\ \tt{\implies} \:CI = 832$

Compound Interest = Rs. 832.

$\therefore$ The Compound Interest is Rs. 832.
