Answer 2

Given :

⬤ Principal = Rs. 72000

⬤ Rate = 6%

⬤ Time = 3 years

To Find :

⬤ Amount .

⬤ Compound Interest.

Formula Used :

$\bf[\:{A=P\:\bigg(1+\dfrac{r}{100}\bigg)^{t}}\:]$

• A = Amount
• P = Principal
• R = Rate of Interest
• T = Time

Solution :

A = P(1 + r/100)^t

A = 72000 (1 + 6/100)³

A = 72000 (100 + 6/100)³

A = 72000 (106/100)³

A = 72000 (106/100)³

A = 72000 (1191016/1000000)

A = 85767552/1000

A = 85767.552

Therefore , Amount is Rs. 85767.552 .

Formula Used :

$\bf[\:{C.I = Amount - Principal}\:]$

• C.I = Compound Interest

Now :

According to the Formula :-

C.I = A - P

C.I = 85767.552 - 72000

C.I = 13767.552

Therefore , Compound Interest is Rs. 13767.552 .
