Calculate the simple interest on 6000 for 3 years at 12% per annum

Simple interest = Principal x Rate x Time

P = 6000, r = 12%, t = 3 years

Simple interest = 6000 x 0.12 x 3
= 2160

Therefore, the simple interest on 6000 for 3 years at 12% per annum is Rs. 2160.

To calculate the simple interest, we can use the formula:

Simple Interest = (Principal Amount) x (Rate) x (Time)

In this case:
Principal Amount (P) = 6000
Rate (R) = 12% per annum
Time (T) = 3 years

Converting the rate to decimal form:
R = 12/100 = 0.12

Substituting the values into the formula:
Simple Interest = 6000 x 0.12 x 3

Calculating the simple interest:
Simple Interest = 2160

Therefore, the simple interest on 6000 for 3 years at 12% per annum is 2160.
