Answer 2

QuestioN :

Find the compound interest and amount of ₹8000 at 5% for 2 years.

GiveN :

• P = ₹8000
• R = 5%
• T = 2 years

To FiNd :

The compound interest and amount.

ANswer :

The compound interest is ₹820 and Amount = ₹ 8820.

SolutioN :

$\sf P =$ ₹$\sf 8000$ ; $\sf R= 5$% ; $\sf T= 2\:years$

$\sf A = P( 1+ \dfrac{R}{100})^2$

$\sf \implies 8000(1+\dfrac{5}{100})^2$

$\sf \implies 8000( \dfrac{100+5}{100})^2$

$\sf \implies 8000\:(\dfrac{105}{100})^2$

$\sf \implies 8000\times \dfrac{105}{100} \times \dfrac{105}{100}=8820$

$\sf Amount =$ ₹$\sf 8820$

∴Compound interest = Amount - Principal

                                   = ₹ ( 8820-8000 )

                                   = ₹ 820

∴Hence, the compound interest is ₹820 and Amount = ₹ 8820.
