Question

find the amount and compound interest of rupees 3150 is invested for 2 years at 4% compound interest pls answer properly, or else will be reported pls answer to this question fast

Answer 1

Given

• Principal= Rs.3150
• Time=2 year's
• Rate = 4%

To Find

• Amount And Compound Interest

Formula Used

• $\underline{ \boxed{ \sf \: A = P \left(1 + \frac{R}{100} \right) ^{n} }}$
• Compound Interest= Amount- Principal

Solution

Putting the value of Principal,Rate and Time In Formula we Get,

${\implies\sf \: A = 3150 \left(1 + \dfrac{2}{100} \right) ^{2}}$

${\implies\sf \: A= 3150 \left( \dfrac{102}{100} \right) ^{2}}$

${\implies\sf \: A = 3150 \left( \dfrac{51}{50} \right) ^{2}}$

${\implies\sf \: A = 3150 \times \dfrac{2601}{2500} }$

${\implies\sf \: A = 63 \times \dfrac{2601}{50} }$

${\implies\sf \: A = 63 \times 52.02}$

${\implies\sf \: A = 3277.26}$

• Amount= 3277.26

$\\\sf Compound ~Interest= Amount- Principal$

$\sf Compound~ Interest= 3277.26-3150$

$~~~~\underline{\boxed {\sf Compound ~Interest= Rs. 127.26}}$

Answer 2

Step-by-step explanation:

compound interest= amount- principal

=3277.26-3150 = 127.26
