Show Answer

Answer:

Correct Answer: B

Solution:

$ Rate=\frac{SI\times 100}{Principal\times Time}=\frac{7200\times 100}{20000\times 3}=12 $ %

$ \therefore $ $ CI=P[ {{( 1+\frac{R}{100} )}^{T}}-1 ] $ $ =20000[ {{( 1+\frac{12}{100} )}^{3}}-1 ] $ $ =20000[{{(1.12)}^{3}}-1] $ $ =20000,[1.404928-1]=Rs\text{.}8098\text{.56} $
