Question

If,
Rate of Interest = ₹10
Time = 4 years
Amount = ₹1330

Find "Principal" and "Interest" using Formulas.

Answer 1

Step-by-step explanation:

We have,

A = 1330, R = 10%, Time n = 4 years

Principal:

A = P(1 + r/100)ⁿ

⇒ 1330 = P(1 + 10/100)⁴

⇒ 1330 = P(11/10)⁴

⇒ P = 908.40

Interest:

C.I = A - P

     = 1330 - 908.40

     = 421.6

Hope it helps!
