## Find amount : Amount = Simple Interest + Principal

 Amount Compound Interest Difference between Simple & Compound Interest

 Formula to calculate amount Amount = Simple interest + Principal Let solve following problems for further understanding: Problem 1 - Find interest on Rs 1000 for 2 years at 5% rate Answer Principal = Rs 1000 Time = 2 years Rate of interest = 5% ```Simple interest = (PRT) / 100 = (1000 X 2 X 5) /100 = Rs 100 Amount = Simple interest + Principal = 100 + 1000 = Rs 1100 ``` Problem 2 - Find interest on Rs 2000 for 2.5 years at 10% rate Answer Principal = Rs 2000 Time = 2.5 years Rate of interest = 10% ```Simple interest = (PRT) / 100 = (2000 X 2.5 X 10) /100 = Rs 500 Amount = Simple interest + Principal = 500 + 2000 = Rs 2500 ``` Problem 3 - Find interest on Rs 5000 for 1 years at 11% rate Answer Principal = Rs 5000 Time = 1 years Rate of interest = 11% ```Simple interest = (PRT) / 100 = (5000 X 1 X 11) /100 = Rs 550 Amount = Simple interest + Principal = 550 + 5000 = Rs 5550 ```
