Question

The SI on a sum of money for 3 years at 12 1/2% per annum is 1,500. What will be the Cl on the sum at
the same rate and for the same period?
so 10% per annum compounded annually for 2 years.​

Answer 1

Step-by-step explanation:

S.I=Rs.340,Time=2 years,R=4%

(i)Let the sum of money be rs.x

S.I=

100

PRT

⇒340=

100

x×4×2

⇒x=

4×2

340×100

=Rs.4250

(ii)C.I for Rs. 4250 for one year payable half-yearly

∴ T=1 year=2 half year,Rate=

2

4

=2%

A=P(1+

T

⇒4250(1+

=4421.70

C.I=A−P

⇒4421.70−4250=Rs.171.70

Answer 2

Answer:

21854.54

Step-by-step explanation:

T=3

SI=1500

R=12.5

P=SI*100/R*T

=1500*1000/125*3

=2400

CI=2400(1+12.5/100)^3

=2400*125/1000*125/1000*125/1000

I hope this helps
