Question

find the compound interest on ₹26000 for 3 years at the rate of 10% per annum compounded annually.​

Answer 1

Answer:

Principal,p=26000

Rate,r=10%

Time,t=3years

As we know that

a=p(1+r/100)^n

a=26000(1+10/100)^3

a=26000×110/100×110/100×110/100

a=34606

ci=a-p

=34606-26000

=8606

Answer 2
