Answer:

Correct Answer: C

Solution:

Interest is compounded half - yearly.

$ \therefore $ R = 20% per annum = 10% half-year T = 2 yr = 4 half - year

$ \therefore $ $ CI=P[ {{( 1+\frac{R}{100} )}^{T}}-1 ] $ $ =1000[ {{( 1+\frac{10}{100} )}^{4}}-1 ] $ $ =1000[ {{( \frac{11}{10} )}^{4}}-1 ] $ $ =1000[ ( \frac{121}{100}+1 )( \frac{121}{100}-1 ) ] $ $ =1000\times \frac{221}{100}\times \frac{21}{100}=Rs.,4641 $
