Question

find the compound interest at 5% per annum for 3 years on tge principal which gives simple interest 2400 rs at the same rate for the same time​

Answer 1

360 is a rate of interest and when you add with 2400+360= 2760 rs

Answer 2

P=S.I×100/R×T

P=2400×100/5×3

P=16,000 rupees

C. I = A-P

A=P(1+R/100)^N

=16000(1+5/100)³

=16000(1+1/20)³

=16000(21/20)³

=16000×21/20×21/20×21/20

=18522 rupees

C. I=A-P

=18522-16000

=2522 rupees
