Ramesh invests Rs. 12800 for three years at the rate of 10% per annum compound interest. Find the sum due to Ramesh at the end of the first year?

Sreedevi replied | 21/11/2016

The amount at the end of Year I is 10% of the principle added to the principle itself. So it would be 12800+(10% of 12800)=14080

The difference between simple interest and compound interest compounded annually on a certain sum of money for 2 years at 4% per annum is Rs 1. What is the sum of rupees?

Ram Mohan replied | 18/11/2016

If 'P' is the Principal Sum , then Compound Interest (CI) @4%, after 2 years is:
CI = P{ (1+4/100) (1+4/100) -1} =P { 1+16/10000 +2*4/100 -1} = P{16/10000+2*4/100}
Simple Interest SI, @ 4% after 2 years is:
SI = P*2*4/100
It is given that, CI - SI= Rs.1, Substituting the values of CI and SI in the above eqn, we get:
P{16/10000 + 2*4/100} - P*2*4/100 =1,...  more»
If 'P' is the Principal Sum , then Compound Interest (CI) @4%, after 2 years is:
CI = P{ (1+4/100) (1+4/100) -1} =P { 1+16/10000 +2*4/100 -1} = P{16/10000+2*4/100}
Simple Interest SI, @ 4% after 2 years is:
SI = P*2*4/100
It is given that, CI - SI= Rs.1, Substituting the values of CI and SI in the above eqn, we get:
P{16/10000 + 2*4/100} - P*2*4/100 =1, ==> P*16/10000 = 1, ==> P=10000/16, ==> p= 625
Therefore, the principal Sum lent was, Rs.625/-
One Can use the Formula
P*(r/100)*(r/100) = d , where, 'P' is Principal Sum, 'r' is rate of interest for a prescribed period, and 'd' is the difference between CI and SI, for two such periods; can be used in this case. «less

Suyash replied | 19/11/2016

Given,
Compound Interest -Simple Interest = 1
P { 1+ ( 4/100) } ^ 2 - P - ( P×4×2 / 100 ) = 1
On solving,
P = 625

Geeta 09/11/2016 in  Compound Interest

The compound interest on Rs 30000 at the 7% per annum is Rs 4347. What is the period (in years)?

Ram Mohan replied | 21/11/2016

The period is 2 years. Very simple solution
30000[ (1+7/100) power n] - 30000=4347 = = > 30000 [ (1+7/100) power n] = 34347==>
[ (1+7/100) power n] = 34347/30000 ==> [ (100+7)/100) power n] = [ (100+7)/100 ) power 2==> n=2

What will be the compound interest on a sum of Rs. 25000 after 3 years at the rate of 12 p.a?

Shikha replied | 23/11/2016

Amount =[25000(1+12/100)3]
=[25000*28*28*28]/25*25*25
=Rs 35123.20
CI = Rs 35123.2+ Rs 25000= Rs 10,123.20.
