Question

if interest = rs 1200 , principal = rs 3000, R = 10% , find Time ​

Answer 1

Solution

Simple Interest

Interest = Rs. 1200

Principal = Rs. 3000

Rate = 10% p.a.

I = $\sf\dfrac{P×R×T}{100}$

T = $\sf\dfrac{100×I}{P×R}$

T = $\sf\dfrac{100×1200}{3000×10}$

T =$\sf\dfrac{12}{3}$

T = 4years.

Additional Information

P = $\sf\dfrac{100×I}{R×T}$

A = P + I

I = A - P

P = A - I

CI = A - P.
