Answer 2

A=P(1+r/100)^n and C.I.=A-P
where A= amount at the end of 'n' cycles
'r' is the percentage rate of interest per cycle
'n' is the number of cycles
'P'is the amount lent or the principal
C.I. is the compound interest
or we can also say
C.I.=P[(1+r/100)^n-1]
note.if the interest is compounded annually,
'n' will be the no.of years and 'r' will be the
annual rate of interest
if the interest is compounded half yearly
'n'=2 times the no. of years and 'r' will be
the annual rate of interest /2 and so on
