Question

.. Find the compound interest on a sum of 78000 for 3 years at the rate of 5% p.a.
​

Answer 1

Answer: CI = A-P

A=?

A= P(1+R/100) Raise to Power N

ATQ, 78000(1+5/100)³

78000(106/100)³

81,900

Amount is 81,900

CI=A-P

81,900 - 78000

= 3,900

Answer 2

Answer:

Compound Interest=₹12,294.75

Step-by-step explanation:

Using the formula:

⇒ $P(1+\frac{R}{100})^{n}$

⇒$78000(1+\frac{5}{100})^3$

⇒$78( 105)(\frac{105}{10} )(\frac{105}{100})$

⇒₹90,294.75= Amount

⇒Amount-Principal=Compound Interest

⇒₹90,294.75-₹78000=₹12,294.75

⇒Compound Interest=₹12,294.75
