Question

p=500 r= 10% p.a t= 2 find ci

Answer 1

HOLA USER ✌

HERE'S YOUR ANSWER FRIEND,

GIVEN : QUESTION,

✏✏

==> p (PRINCIPAL) = 500

r( rate of interest) = 10%

Time = 2 years

WE KNOW,

FORMULA FOR COMPOUND INTEREST,

==> AMOUNT = p( 1 + r/100 )^t

==> AMOUNT = 500( 1 + 10/100)²

==> AMOUNT = 500( 1 + 1/10)²

==> AMOUNT = 500(11/10)²

==> AMOUNT = 605

NOW, COMPOUND INTEREST

= AMOUNT - PRINCIPAL

==> 605 - 500

==> 105

IS THE REQUIRED ANSWER.

HOPE IT HELPS YOU

Answer 2

Amount =
$principal \times ( { \frac{rate}{100} + 1})^{time}$

$500 \times( 1 + \frac{10\%}{100} )^{2}$
$500 \times ( \frac{1}{100} + 1) ^{2}$

$500 \times (\frac{1\ + 11}{10} )^{2}$

$500 \times (\frac{11}{10})^{2}$

$500 \times \frac{11}{10} \times \frac{11}{10}$

605 is amount.

Compound Interest = Amount - Principal
C I = ₹605 - ₹500
C I = ₹105 .
