Question

*What is the compound interest on Rs. 200 for 1 year at 10% rate compounded half-yearly*​

Answer 1

Answer:

Principal = ₹200

Time = 1 year compounded half yearly

Rate = 10%

Now,

For 1st ½ year,

P = ₹200

R = 10%

T = ½ year

Interest =P*R*T/100

Interest=Rs 10

Amount =P + I

Amount =200+10=210

For 2nd ½ years

P = ₹210

R = 10%

T = ½ year

Interest=rs 210*10*1/10*2

=rs 21/2

=Rs 1.5

Amount=210+1.5=Rs 211.5

C.I =Required amount-Initial amount

=Rs 211.5-200

=Rs 11.5answer
