Question

find principal= 6500 , S.I=975 ,time =5year rate=?​

Answer 1

Answer:

Step-by-step explanation:

S.I= PxRxt/100

975=6500xRx5/100

975=65xRx5

R=975/65x5

R=975/325

R=3%

Answer 2

Answer:

Rate = 3 %

Step-by-step explanation:

Given that ;

Principal = 6500

Time = 5 years

S.I ( Simple Interest ) = 975

Then, Rate =?

Let's see the relationship between the principal, rate, time and Simple interest.

Simple Interest = $\frac{P \times R \times T}{100}$

⇒ 975 = $\frac{6500 \times R \times 5}{100}$

On cross multiplying :

⇒ 6500 * R * 5 = 975 * 100

⇒ 32500 * R = 97500

⇒ R = $\frac{97500}{32500}$

⇒ R = 3 %

Hence, the rate is 3 % per year.
