Question

What sum will yield rs 1416 at 19/2% per annum after 2 year​

Answer 1

Answer:

P =  Rs 1018.71 by SI

P = Rs 991.58 by CI

Step-by-step explanation:

By Simple Interest  Method

Amount = 1416

R = 19/2%

T = 2

P =?

Amount = P + SI

∴ P = A - SI = 1416 - SI

Now, SI = PRT/100

SI = (1416 - SI)19.5 × 2/100

100SI = (1416 - SI)×39 = 55224 - 39SI

100SI + 39SI = 55224

SI = 55224/139 = 397.29

∴ P = 1416 - 397.29

P = 1018.71

By Compound Interest  Method

Amount = 1416

R = 19/2%

n = 2

P =?

Amount = P(1 + R/100)ⁿ

1416 = P(1 + 19.5/100)²

= P(1.195)² = P(1.428025)

P = 1416/1.428025

P = 991.58
