Question

What is the compound interest on Rs 38000 at 20% per annum for a period of

3/2

years compounded semi - annually​

Answer 1

Answer:

Principal = Rs 38000

Time =3/2 yrs

Rate of Interest = 20%

Compound Interest is calculated semi-annually , so time will be double (Time =3/2×2=3yrs) and also rate will be halved (Rate=20%/2=10%)

Compound Interest calculated Semi-annually = P(1+R/100)^n

=38000×(1+10/100)^3

=38000×11/10×11/10×11/10

=38×11×11×11

=Rs 50,578(Answer)

Answer 2

answer

p =38000

T=3/2=2year semi annually

rate equals to 20% =10%semi annually

amount=principal [ 1+r%/100]n

amount=38000(1+10%/100)3 power h

38000(100+10/100)3power h

38000(110/100)3

3800×1.1×1.1×1.1

=50578

compound interest =amount-principal

50578-38000

12578
