To Find : Interest in 1st , 2nd & 3 Year
Difference in CI & SI in3 Years
Which one is better
Solution:
P = 15000
R = 9 %
T = 3 Years
Interest 1st Year = P ( 1 + R/100)¹ - P = P * R/100 = 15000 * 9 /100 = 1350
Amount after 1 Year = P ( 1 + R/100)¹ = 15000(1 + 9/100)¹ = 16350
Interest 2nd Year =P ( 1 + R/100)² - P ( 1 + R/100)¹ = P ( 1 + R/100)(R/100) = 1,471.5
Amount after 2 Year = P ( 1 + R/100)² = 17,821.5
Interest 3rd Year =P ( 1 + R/100)³ - P ( 1 + R/100)² = P ( 1 + R/100)²(R/100) = 1,603.935
Amount after 3 Year = P ( 1 + R/100)³ = 19,425.435
interest in 3 Years = P ( 1 + R/100)³ - P = 19,425.435 - 15000
= 4,425.435
SI = 15000 * 9 * 3/100 = 4050
Compound interest is better
