Given
Principal = 600
Rate for half - yearly =10%÷2 = 5%
time for half -yearly = 1×2 = 2 year
we denote principal=p , rate =R and time =t
A = P (1+R÷100 ) ^Time
A= 600 ( 1+5÷100 ) ^2
A 600 ( 21÷20 ) ^2
A=600 × 21÷20×21÷20
A= 661.5
C I =A-P
CI = 661.5-600.0
CI =61.5
Principal = 600
Rate for half - yearly =10%÷2 = 5%
time for half -yearly = 1×2 = 2 year
we denote principal=p , rate =R and time =t
A = P (1+R÷100 ) ^Time
A= 600 ( 1+5÷100 ) ^2
A 600 ( 21÷20 ) ^2
A=600 × 21÷20×21÷20
A= 661.5
C I =A-P
CI = 661.5-600.0
CI =61.5
