Question

find the compound interest on rupees 4000 for 3 years at 5% per annum​

Answer 1

Answer:

Given,

P=4000

T=3years

R=5%

For the first year

P=4000

T=1year

R=5%

I=PTR/100

=4000*1*5/100

=200

A=P+I

= 4000+200

=4200

for the second year

P=4200

T=1yr

r=5%

I=PTR/100

4200*1*5/100

=210

A=P+I

=4200+210

=4410

for the third year

P=4410

t=1 year

r= 5%

I=PTR/100

4410*1*5/100

=220.5

C. I= F. A-O. P

=220.5-4000=3779.5
