The compound interest on Rs.2,000 at 10% per annum for 3 years payable half yearly is

a) Rs.600
b) Rs.630
c) Rs.660
d) Rs.680

• amt=2000(1+r/2/100)^2n formulae as it is half yearlly
  
  amt=2000(1+1/20)^4
  amt=2680.19
  ci= 2680.19-2000 = 680.00

• Per year 10% so per half year it is 5%
  5% of 2000 is 100
  5%of (2000+100) i.e 5% of 2100 is 105
  5% of 2205 is 110.25
  100+105+110.25=315.25
  315.25 is CI for 1.5 years
  So CI for 3 years will be 315.25×2=630.50
